I am trying to render single react component with different properties at different div id
index.html:
<div class="container" id="root1"></div>
<div class="container" id="root2"></div>
There are two hyperlinks and onClick will catch the id of the hyperlink, I have bound root1 and root2 to both the hyperlinks and calls the function(prop, containerID)
file.js:
function(prop, containerID){
ReactDOM.render(<component prop={prop}/>, document.getElemntById(containerID));
}
after this statements i can see only 'prop2' at both the divisions 'root1' and 'root2' and if i change the order of ReactDOM.render by 'root2' and then 'root1', then only 'prop1' is visible at both 'root1' and 'root2'.
But I need 'prop1' at 'root1' and 'prop2' at 'root2'.
Is there anything I need to add more to the above code or any other alternative way to implement this view?

I have popup form component which has form header body footer. How can I update CSS of those HTML elements with the help of form container componentID.
I have tried these:
getComponent('stakeholderAddUserWindow').update({height: 1900});
getComponent('stakeholderAddUserWindow').addClass('newclass');
getComponent('stakeholderAddUserWindow').style: 'background-color: #5E99CC';
getComponent('stakeholderAddUserWindow').update({style: 'background-color: #5E99CC;'});
I have other doubt how to traverse from the container to inner child elements, here I have 3 child elements with classes x-header, x-body, x-footer. I want to apply CSS to the body.
<div class="x-window flex-window deploymentPlanWindow x-layer x-
window-default x-border-box" id="stakeholderAddUserWindow-1502"
componentid="stakeholderAddUserWindow-1502">
<div class="x-window-header x-header"id="stakeholderAddUserWindow-
1502_header">header</div>
<div class="x-window-body x-body"id="stakeholderAddUserWindow-
1502_body">body</div>
<div class="x-window-footer x-footer"id="stakeholderAddUserWindow-
1502_footer">footer</div>
</div>
Ext.get(Ext.query('.x-window > .x-window-header')).setStyle('background', 'blue');
Above one not working
For editing styles use 'setStyle' function on components or elements
And for adding and removing classes use addCls and removeCls functions
getComponent('stakeholderAddUserWindow').setStyle('height', '437px');
I am working on an admin panel application which is based on AngularJS 1.5. It is structured as follows:
There is a main component called app, in which I am using all other components.
app.html
<div class="wrapper">
<message-component></message-component>
<header></header>
<leftbar></leftbar>
<body></body>
</div>
In the body component, I am using ui-view to render my component based on the current route.
At one time, three components are usually present : header, leftbar and body. I am using ng-if directive in my leftbar component in which I am calling a function.
leftbar.html
<li ng-if="leftbar.hasPermission('FOO')">
<a ui-sref="foo">
<span>Demo Page</span>
</a>
</li>
leftbar.controller
class LeftbarController {
constructor() {}
hasPermission(name) {
return user[name];
}
}
It basically shows the <li> if the user has a permission named "FOO".
Now, simultaneously my body component is also visible to the user and there is an input field present inside that, so whenever I write something in that field hasPermission method also gets called which is present in a different component.
So what can be the issue here? Why scopes are behaving like this ?
I'm creating a reusable item picker component using Angular 1.5. The picker has a search field and a list of items to choose from. An example use case for the picker is a popup where the user selects some items and then has a "Continue" button to proceed.
Conceptually, the search field and the list of items belong to the component and the "Continue" button belongs to the surrounding dialog. However, I want to position the button next to the search field. In some cases there are no extra buttons, sometimes one extra button, sometimes two.
Something like this:
What is the best way to create such a component?
Options I've thought of:
Create a component / directive for the item picker, put the button before or after the directive in the HTML, and use CSS to position the button.
Here the positioning of the button is ugly and fragile, as it's not in the proper position within the HTML. It would probably need a wrapper div and absolute positioning on top of the picker component:
<div style="position: relative">
<item-picker></item-picker>
<button name="Continue" ng-click="submit()" style="position:absolute; top:5px; right: 5px"></button>
</div>
Somehow pass the buttons and callbacks as parameters to the item picker component. Here the ugliness is in the hard-coding of the buttons and styles and amount of buttons:
<item-picker btn1-text="Continue" btn1-style="primary" btn1-callback="submit()" btn2-text="Cancel" btn2-style="secondary" btn2-callback="cancel()"></item-picker>
I'm unsure whether the button configuration and callbacks could be passed as a single configuration object. I'm mainly concerned about the callback functions, whether they will work properly if passed through a configuration object instead of proper '&' callback binding.
Stop trying to make the picker into a component / directive and just use <ng-include> to include the picker code which reads the button configuration from the scope. Ugliness is in lack of scoping and not using components.
Is there some best practise for such cases?
One possible solution is to use ng-transclude, so your code could look something like:
Markup
<item-picker>
<button ng-click="parentScopeFn()">Btn 1</button>
...
</item-picker>
Directive
angular.module('myApp', [])
.directive('itemPicker', function() {
return {
restrict: 'E',
transclude: true,
scope: {
...
},
templateUrl: 'item-picker.html'
};
});
itemPicker template markup
<div class="item-picker">
<div class="item-picker-controls">
<div class="item-picker-search"><input type="search" ng-model="..."></div>
<div class="btn-group" ng-transclude></div>
</div>
<ul class="item-picker-list">
<li ng-repeat="item in items" ng-bind="item"></li>
</ul>
</div><!-- end item-picker template -->
Of course the above code is just an example and is making a lot of assumptions about your itemPicker component. Also, you'll still need to use CSS to position your buttons, but it might be easier to reason with b/c it'll be in the context of your component.
Note
You could also make use of "multi slot transclusion". This is probably useful in cases where the number and type of buttons you'll have is predictable and you want them arranged in a consistent way no matter how they are placed in the markup.
Hope this helps.
I'm attempting to learn AngularJS (background in BackboneJS). I have a div with some content inside, and I hope to render this div as a modal upon clicking inside of it:
<div class="stickynote"> Content here </div>
My thinking is to add a modal class that I can style in CSS. However, I'm not too sure how to add the modal class upon clicking (and conversely, removing the modal class upon clicking after the modal is rendered). Would I have to use ng-click and somehow set the class property from the JavaScript (myApp.js) file?
If you want to use your own modal styling and if you simply want to achieve adding an extra item to class attribute of your element, you can use a combination of ng-class and ng-click:
<div class="stickynote"
ng-class="{yourModalCSSClass: isModalOpen}"
ng-click="isModalOpen = true">
And somewhere else, you need another ng-click to turn it off:
<button ng-click="isModalOpen = false">Close modal</button>
Beware that both div and button must be in the same scope hierarchy to be able to use the same isModalOpen value. And by the way, I haven't tried this code but this should give you an idea. If you have a controller/directive, you can set isModalOpen from there by introducing functions in the scope:
// controller
$scope.toggleModal = function () {
$scope.isModalOpen = !$scope.isModalOpen;
}
<div ...
ng-click="toggleModal()">
<button ng-click="toggleModal()">...
If you're open to using a third-party solution, ng-dialog is an outstanding solution for modals+Angular.

I am somewhat new to using Angular and AngularStrap directives. I need to use the tab directive with static markup like the example:
<div data-fade="1" bs-tabs>
<div data-title="'Home'"><p>Static tab content A</p></div>
<div data-title="'Profile'"><p>Static tab content B</p></div>
</div>
On another part of the page I would like to display a div only when the first tab is selected. The div is not part of the tabs, but is in the same overall controller. How can I show/hide this div based on the selected tab?
Something like this?
<div ng-show="???? active tab stuff here ????">Home tab is selected</div>
Thanks for any help.
As shown in the example on the AngularStrap page the active tap is stored in
tabs.activeTab
So you can use this property to conditionally show display something else like so
<div ng-show="tabs.activeTab == 0">The first tab is active</div>
UPDATE
Even with non object tabs you can just bind a model against the bs-tabs to store the active ID like so:
<div data-fade="1" ng-model="tabs.activeTab" bs-tabs>
Here is an updated plnkr. (Click on the 3rd tab and see the 'Test' text appear)
I found somewhat of a hack to resolve this issue for now. This does not seem like the best approach, so if someone has a better idea, please share.
I realized that the bsTabs directive is creating data-toggle attributes for each tab. By watching the data-toggle shown event, I am able to recognize the tab change and display the div. The controller code looks like this:
$scope.HomeTabSelected = true;
function watchTab() {
$('a[data-toggle="tab"]').on('shown', function (e) {
$scope.$apply($scope.HomeTabSelected = (e.target.innerHTML == "Home"));
})
}
setTimeout(watchTab, 2000); // setTimeout necessary to allow directive to render
and the HTML div uses ng-show.
<div ng-show="HomeTabSelected">Home tab is selected</div>
