So I'm switching an internal style guide for a site we're working on from regular html to use reactjs. I've got example code and I'm using highlighting with prism.js. The highlighting seems to work fine, but line breaks don't. Even putting in br tags after every line has no effect. Anyone have any thoughts on this?
Just some example code:
var Example = React.createClass({
render: function() {
return (
<div class="highlight">
<pre>
<code class="language-markup">
<label class="select">
<select class="selector">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
</label>
</code>
</pre>
</div>
);
}
});
React.render(<Example />, document.getElementById('example'));
When it renders it looks like this.
<label class="select"><select class="selector"><option value="1">1</option><option value="2">2</option><option value="3">3</option><option value="4">4</option><option value="5">5</option></select></label>
But I expect it to look like this:
<script src="https://cdnjs.cloudflare.com/ajax/libs/prism/0.0.1/prism.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/prism/0.0.1/prism.min.css" rel="stylesheet"/>
<div class="highlight">
<pre>
<code class="language-markup">
<label class="select">
<select class="selector">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
</label>
</code>
</pre>
</div>
Anyone know of a way to preserve the line breaks?
You can just code like this:
var Example = React.createClass({
render: function() {
return (
<div class="highlight">
<pre>
<code class="language-markup">
{`
<label class="select">
<select class="selector">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
</label>
`}
</code>
</pre>
</div>
);
}
});
Demo is here.
The only shortage is the indent.
First: Use ReactDOMServer.renderToStaticMarkup to render component to string
var inner = ReactDOMServer.renderToStaticMarkup(
<label className="select">
...
</label>
);
After Use JS Beautifier to prettify your string
inner = html_beautify(inner);
Finnaly Insert it to your code as string
<code className="language-markup">
{inner}
</code>

Just give children like this and it will work like a charm.
<pre>
<code class="language-markup">
{`
.ui-datatable table {
border-collapse:collapse;
width: 100%;
table-layout: fixed;
}
`}
</code>
</pre>

How to store multiple values in state
to do this ,you will need to define state for all four select box like this
const [seleccedValue1,setSelectedValue1]=useState(null);
const [seleccedValue2,setSelectedValue2]=useState(null);
const [seleccedValue3,setSelectedValue3]=useState(null);
const [seleccedValue4,setSelectedValue4]=useState(null);
then you will need to handle on change event of each select box like this
<select onChange={(e)=>{setSelectedValue1(e.target.value)}}>
<option value="essay">Paraphrasing</option>
<option value="Custom Writing">Custom Writing</option>
<option selected value="Dissertation">Dissertation</option>
<option value="Research Paper">Research Paper</option>
<option value="essay">Essay</option>
<option value="Term Paper">Term Paper</option>
<option selected value="Admission Essay">Admission Essay</option>
<option value="Coursework">Coursework</option>
<option value="Book Review">Book Review</option>
<option selected value="Paraphrasing">Essay</option>
<option value="Physics Paper">Physics Paper</option>
</select>
you can do the same for other select boxes as well
Please checkout this question:
It was already answered here:
React JSX: selecting "selected" on selected <select> option
Here is how you store value of any input field in useState();
const [selected,setSelected] = useState({});
function handleChange(event){
setSelected({...selected,[event.targe.id]=event.target.value});
}
return(
<select
id={"id_0"}
value={selected["id_0"]}
onChange={(event)=>(handleChange(event))}>
......."your code continue here"
and here is how you handle multiple input fields.
<select id={'id_1'} value={selected['id_1']}
onChange={(event)=>(handleChange(event))}/>
<select id={'id_2'} value={selected['id_2']}
onChange={(event)=>(handleChange(event))}/>
when am using this code.selected value shown as empty.i want select 1st value as one.
<select class="form-control" name="cityID" id="Select1" ng-change="RoomSelect()" ng-model="sRoom">
<option value="1" selected="selected">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
</select>
When am using ng-model at the time default value selected as empty.otherwise its ok.
Try init sRoom model in controller
$scope.sRoom = 1;
also its better use ng-options instead of repeat option in select tag.
Demo
var app = angular.module('anApp', []);
app.controller('aCtrl', function($scope) {
$scope.sRoom = 1;
$scope.chooses = [{"key":"one","value":1},{"key":"Two","value":2},{"key":"Three","value":3}];
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="anApp" ng-controller="aCtrl">
<select ng-change="RoomSelect()" ng-model="sRoom" ng-options="k.value as k.key for k in chooses">
</select>
</div>
Try this
<select class="form-control" ng-init="sRoom=1" name="cityID" id="Select1" ng-change="RoomSelect()" ng-model="sRoom">
<option value="1" selected="selected">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
</select>
You can also use ng-init
<select class="form-control" ng-init="sRoom=1" name="cityID" id="Select1" ng-change="RoomSelect()"
I want to link two select in angularjs. when first select value in(3,4) the second select show.
code:
<select ng-model="type">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select>
<select ng-show="type in [3,4]">
...
</select>
But it is not work.
Thanks.
Here is fiddle :-)
http://jsfiddle.net/svbxwphr/
<div ng-controller="AjaxCtrl">
<h1>AJAX - Oriented</h1>
<div>
Country:
<select id="country" ng-model="country" ng-options="country for country in ['1','2','3','4']">
<option value=''>Select</option>
</select>
</div>
<div>
City: <select id="city" ng-disabled="!cities" ng-model="city" ng-options="city for city in cities"><option value=''>Select</option></select>
</div>
Controller:-
function AjaxCtrl($scope) {
$scope.$watch('country', function(newVal) {
if (newVal==3|| newVal==4){
$scope.cities = ['3', '4'];}
else{
$scope.cities = [];
}
});
}
there is no syntax for in in ng-show.
you have to write long syntax.
<select ng-model="type">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select>
<select ng-show="type === '3' || type === '4'">
...
</select>
I have this HTML code (no, I can not to convert it in a ng-options):
<form>
<div class="list">
<div style="margin-bottom: 20px;">
<label class="item item-input item-select">
<div class="input-label">
Price From (start)
</div>
<select required id="priceForm" ng-model="search.priceFrom" ng-init="'search.priceFrom = searchParams.priceFrom'">
<option value=0>All</option>
<option value="100">100</option>
<option value="200">200</option>
<option value="500">500</option>
<option value="700">700</option>
<option value="1000">1000</option>
<option value="1500">1500</option>
<option value="2000">2000+</option>
</select>
</label>
</div>
<div>
<label class="item item-input item-select">
<div class="input-label">
Vacation Days (start)
</div>
<select required ng-model="search.vacationDays">
<option value=0 >All</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10+</option>
</select>
</label>
</div>
</div>
</form>
I want this:
The first time that I see this page the values of both select must be "All" (value = 0), and I think that I need only to add "required" but it does no work.
And for every next times the default value need to be the value inside searchParams.priceFrom (it is a variable in my $scope).
Where is my error ?
Thanks.
M.
Since both selects are bound to your search.vacationDays && search.priceFrom all you would need to do in your controller is something like:
$scope.search.priceFrom = 0;
$scope.search.vacationDatys = 0;
Please see demo below
just set your serach obj in controller
$scope.search = {
priceFrom: 0,
vacationDays: 0
}
var app = angular.module('app', []);
app.controller('fCtrl', function($scope) {
$scope.search = {
priceFrom: 0,
vacationDays: 0
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app">
<div ng-controller="fCtrl">

I expect the following code to render a drop down list with the third option selected by default. However, when I bind the select with angularjs, the default selection disappears. Any thought?
var myApp = angular.module('myApp', []);
...
<div>
<select id="myselection" ng-model="selectedColors">
<option value="1" >Red</option>
<option value="2">Blue</option>
<option value="3" selected="selected">Green</option>
</select>
<div>
Selected Colors: {{selectedColors }}
</div>
</div>
Here's a working example: http://jsfiddle.net/TXPJZ/134/
Thanks!
The easiest way to fix your implementation is to use ng-init.
<div>
<select id="myselection" ng-init="selectedColors=3" ng-model="selectedColors">
<option value="1">Red</option>
<option value="2">Blue</option>
<option value="3">Green</option>
</select>
<div>Selected Colors: {{selectedColors }}</div>
</div>
Try it on FIDDLE.
Angular overrides the "selected" property when you bind the select to a model. If you inspect the rendered DOM you will find that a new item has been added:
<option value="? undefined:undefined ?"></option>
In order to automatically select the third option you need to pre-populate the model in scope. There are a few ways to do this, including wrapping the select in a controller:
<div ng-controller="MyCtrl">
<select id="myselection" ng-model="selectedColors">
<option value="1">Red</option>
<option value="2">Blue</option>
<option value="3">Green</option>
</select>
<div>Selected Colors: {{selectedColors }}</div>
And then defining that model in the controller.
var myApp = angular.module('myApp', [])
.controller('MyCtrl', ['$scope', function ($scope) {
$scope.selectedColors = 2;
}]);
Here's a running example.
http://jsfiddle.net/93926/
Alternatively, you could just initialize it using ng-init such as in this example:
<div ng-init="selectedColors=3">
http://jsfiddle.net/9JxqA/1/
EDIT: Removed the selected property in the first example, it's no longer needed.
By adding option with empty value to select and initializing selectedColors to empty string(ng-init="selectedColors=''"), we can see 'select Color' option on top instead of having first color to be selected defaultly:
<div>
<select id="myselection" ng-init="selectedColors=''" ng-model="selectedColors">
<option value="">Select Color</option>
<option value="1">Red</option>
<option value="2">Blue</option>
<option value="3">Green</option>
</select>
<div>Selected Colors: {{selectedColors }}</div>
Try it on Fiddle http://jsfiddle.net/CodecPM/qxyckf7u/
You need to do only two things
1)ng-init="days='noday'"
2)ng-selected="true"
<select class="filtersday" ng-init="days='noday'" ng-model="days">
<option ng-selected="true" value="noday">--Select Day--</option>
You should use single quote to work per
<select ng-model="liveDataType" ng-init="liveDataType='1'" class="form-control input height" required>
<option value="1">Running data</option>
<option value="2">Rest Data</option>
<option value="3">All Data</option>
</select>
Use ng-selected="true"
Check the below code:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<select ng-model="foo" ng-app >
<option value="1">1</option>
<option ng-selected="true" value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
