I'm using the following script to validate a string.
var m;
var re = /([7]{1}[8,5]{1}[0-9]{2}[ ][0-9]{3}[ ][0-9]{3})[a-zA-Z0-9_.\- ]*([0-9]{6})/; // VW MQB
if ((m = re.exec(value)) !== null) {
if (m.index === re.lastIndex) {
re.lastIndex++;
}
return m;
}
The result is an array. Now, I want to delete the spaces in all values. Futhermore I want to prepend one "0" (Zero) at the last value.
Is it possible without dissolve the array and afterwards to create an new array?
Thank you for your help!

Sure, just use a loop:
var n;
for (n = 0; n < m.length; ++n) {
m[n] = m[n].replace(/ /g, ""); // Remove spaces
}
m[m.length-1] = "0" + m[m.length-1]: // Add "0" before last entry

I am trying to count the number of a specific field which is not empty and would like to use an array to store the field names based on whether they exist in the PDF form.
My code looks like this so far and it works as long as the field names in the array exists, if that field does not exist then the code breaks.
The SiteDeficiency_DeficiencyNumber_# could have 0 instances or anywhere up to 50 instances or so.
I did find that you can check if a name exists with this code but I can't seem to get it to work.
Any help is appreciated. I have coded simple things but maybe this is just too advanced for me.
This is what my code looks like so far:
var aFields = new Array("SiteDeficiency_DeficiencyNumber_1",
"SiteDeficiency_DeficiencyNumber_2",
"SiteDeficiency_DeficiencyNumber_3",
"SiteDeficiency_DeficiencyNumber_4",
"SiteDeficiency_DeficiencyNumber_5",
"SiteDeficiency_DeficiencyNumber_6");
var count = 0;
for (i = 0; i < aFields.length; i++) {
if (this.getField(aFields[i]).valueAsString != "") count++
}
event.value = count;
I tried incorporating this too
if(document.forms[0].SiteDeficiency_DeficiencyNumber_1)
{
...
}
I would really like the array at the beginning to populate with only the SiteDeficiency_DeficiencyNumber_# fields that exist and then have the array looped through to count which fields are not blank.
I tried doing this but still does not work.
var aFields = [];
for(i = 1; i <101; i++)
{
if(document.forms[0].("SiteDeficiency_DeficiencyNumber_"+i).valueAsString.length > 0) //Checks if field exists
{
aFields.push("SiteDeficiency_DeficiencyNumber_"+i); //adds field name to array
}
}
var count = 0;
for (a = 0; a < aFields.length; a++) {
if (this.getField(aFields[a]).valueAsString != "") count++ //counts field if not empty
}
event.value = count;
Try this code:
var count = 0;
for(var i = 0; i < this.numFields; i++)
{
if (this.getNthFieldName(i).indexOf("SiteDeficiency_DeficiencyNumber")!= -1){
if (this.getField(this.getNthFieldName(i)).valueAsString != "")
count = count +1
}
}
event.value = count;
The first if statement will check if name of the field contain string SiteDeficiency_DeficiencyNumber. If SiteDeficiency_DeficiencyNumber is present in the field naem then it will check the field value and increment accordingly.

I am trying to test if a specific element in an array is a range of characters, from a-z lowercase. what am I doing wrong? I am very new to coding (1 month in) and I am probably trying to do stuff thats too hard for me.
var array ["a","b","c"];
var myRegularExpression = /[a-z]/;
if (myRegularExpression.test(array[index])) {
//do stuff
}
To give you a working example as #Tushar mentioned:
var arr = ["a","b","c","123"];
var myRegularExpression = new RegExp("^[a-z]+$");
var matchCount = 0;
for (var index = 0; index < arr.length; index++) {
if (myRegularExpression.test(arr[index])) {
//do stuff
matchCount += 1;
}
}
document.getElementById("result").innerText = matchCount;
Number of elements matching the regex "^[a-z]+$":
<div id="result"></div>
I'm using a for loop to get 6 random numbers between 1-20, using indexOf to omit duplicates, and pushing them to an array.
However, I always want 6 items in the array, so I'd like duplicates to be replaced. In my naive code duplicates are simply omitted, which means that sometimes I'll get less than 6 in the array. How do I replace the omissions to fill those 6 array slots?
function rolld(event:MouseEvent) {
for (i = 0; i < 6; i++){
d = (Math.floor(Math.random() * (1 + d_hi - d_lo)) + d_lo);
if (rollArray.indexOf(d) < 0){
rollArray.push(d);
}
}
trace (rollArray);
}
Still very new to this. Thanks for any help!
When you get an element from array with 20 elements, try to remove it from array.
function rolld(event:MouseEvent) {
var elements:Array = [];
for (var i:int = 1; i <= 20; i++)
{
elements.push(i);
}
for (i = 0; i < 6; i++){
d = (Math.floor(Math.random() * elements.length);
rollArray.push(d);
//remove the element
elements.splice(d, 1);
}
trace (rollArray);
}
I believe is something simple but obviously not simple enough :). Any ideas how to check if a value already exists in the Array before adding the value using FOR loop?
I have this so far and it doesn't work as I want to because the Array can contain duplicate values!
var n:int = 5;
var cnt:int;
for (var i = 0; i < n; i++)
{
cnt = randomThief();
for (var a = 0; a < loto5.length; a++)
{
if (loto5[i] == cnt)
{
loto5[i] = cnt;
}
}
}
You can use the indexOf() method of the Array class to check if the value exists like this :
var index:int = loto5.indexOf(cnt);
indexOf() returns a -1, if the value doesn't exist. Here is an example of how to do a check :
if (loto5.indexOf(cnt) >= 0)
{
// do something
}
for (var a = 0; a < loto5.length; a++)
{
cnt = randomThief();
if (loto5.indexOf(cnt) == -1) //if cnt isn't in array do ...
{
trace (cnt+" is not in Array");
loto5[a] = cnt;
}
}
Works, simple and beauty :)
I have two arrays, namely combo and truecombo. The user fills the combo with MovieClips by clicking on various buttons on the stage, truecombo is the correct combination.
At any given point (enterFrame) Flash is checking whether the two are the same, if yes, then do some stuff. For the time being this is my code (altered several times, like with Typecasting the indices, adding .parent at the end of combo[o] etc. 2 things will happen, either one or the other.
Either the statement will not be satisfied, at which point the adding and chopping of the combo array will continue, or the condition will be instantly met when combo.length = 6. Check my code.
UPDATE: I have a dropbox file with my current code. Click this for FLA link and here is the SWF link stripped down as always for ease and security.
/*stage.*/addEventListener(Event.ENTER_FRAME, checkthis);
function checkthis(e:Event)
{
for(var o:int=0;o<= combo.length; o++)
{
if((combo[o] == truecombo[o]) && (combo.length==truecombo.length))
{
equal=true;
}
}
if (equal==true)
{
stage.removeEventListener(Event.ENTER_FRAME, checkthis);
endSeq();
}
}
function endSeq():void
{
bravo.play();
for (var i:int = 0; i < combo.length; i++)
{
var element:DisplayObject = combo[i];
element.parent.removeChild(element);
}
firebb.gotoAndPlay(2);
windbb.gotoAndPlay(2);
spiritbb.gotoAndPlay(2);
earthbb.gotoAndPlay(2);
}
This is how I push my new elements to the combo array.
function add(element:DisplayObject)
{
twist.gotoAndPlay(2);
element.width = WIDTH;
element.height = HEIGHT;
if (this.combo.length >= MAX_ELEMENTS)
{
removeChild(this.combo.shift());
}
this.combo.push(element as DisplayObject);
this.addChild(element);
this.reorder();
}
function reorder()
{
for (var i:int = 0; i < combo.length; i++)
{
var element:DisplayObject = combo[i];
element.x = OFFSET_X + (i * SEP_X);
element.y = OFFSET_Y;
}
}
And this is how I have my truecombo and its contents created.
var fireb:firebtn = new firebtn();
var spiritb:spiritbtn = new spiritbtn();
var earthb:earthbtn = new earthbtn();
var windb:windbtn = new windbtn();
var combo:Array=new Array();
const truecombo:Array = [fireb,windb,spiritb,windb,earthb,fireb];
Sorry for the lack of comments, I'd guess it's pretty self-explanatory. Thanks in advance.
I believe combo[o] & truecombo[o] are two instances of the same class & you want them to be matched. If that is the case you may consider :
getQualifiedClassName(combo[o]) == getQualifiedClassName(truecombo[o])
To match the way you did, you must ensure the objects lying inside truecombo be referring to the same ones on stage & not new instances.
EDIT:
It seems you do not break the loop when the match is a success. Use this instead :
function checkthis(e:Event)
{
for(var o:int=0;o<= combo.length; o++)
if((combo[o] == truecombo[o]) && (combo.length==truecombo.length)) {
equal=true;
break;
}
if (equal) {
stage.removeEventListener(Event.ENTER_FRAME, checkthis);
endSeq();
}
}
Here's a really simple loop:
var equal:Boolean=true
if(combo.length == truecombo.length) {
for(var i:int=0; i<combo.length; i++) {
if(combo[i] != truecombo[i]) {
equal=false;
break;
}
}
} else {
equal=false;
}
if(equal) {
//do whatever
}
This assumes both are equal, until we find out otherwise. So if the lengths are different, they are not equal. If the ith element is different, they are not equal.
In the end, you check if your flag equal is true and do whatever you want to do.
