JQuery :: .length Always Returns True
Mar 18, 2010
I'm brand new to jquery, and am trying to set up a dynamic navigation dropdown which is populated with XML by our system (which I can't change.) For some reason, IE6 is showing space where the unused <li></li> tags are. I am trying to create a jquery code which will detect whether or not a link is present in the <li> so I can turn the display off or on dynamically. The relevant jquery code is here:[code]It should eventually appear like this, the way it does in Firefox due to CSS styling:[code]Which means that somehow, it is reading the <a> even when there isn't one.

This is driving me freaking crazy. I have a RegExp, and a String. When I alert RegExp.test(String), I get "true." Sweet. Then I run String.replace(RegExp, ""), in an attempt to get rid of whatever was matched. But that does not change the string at all.
Am I misunderstanding replace, or what?

I have an object: Myobject and properties for the object: Myobject.color, Myobject.width, Myobject.height The scripts returns TRUE if I query Myobject.color or Myobject.width etc. I want to loop through de properties like so:
Code:
var properties = ['color', 'width', 'height']
for (var i=0; i<properties.length; i++) {
Myobject.properties[i]; // Returns UNDEFINED
}
How to make it works? (Should returns TRUE)

New to javascript and I have the following code in onSubmit() validation:
else if (cofaCOURRIEL == null || cofaCOURRIEL == "") {
alert('Le champ COURRIEL doit être rempli.');
document.forms["COFA_AIG"] ["COURRIEL"].focus();
return false;
}
else if (cofaCOURRIEL) {
if ( (atPOS < 1) || (dotPOS < atPOS + 2) || ((dotpos + 2) >= cofaCOURRIEL.length) ) {
alert('Adresse de courriel invalide.');
document.forms["COFA_AIG"] ["COURRIEL"].focus();
return false;
}}
else if (cofaDATE == null || cofaDATE == "") {
alert('Le champ DATE doit être rempli.');
document.forms["COFA_AIG"] ["DATE"].focus();
return false;
}
I understand it is not the best way to validate client side, but I will be doing php server side validation as well. My problem is that once the variable "cofaCOURRIEL" is valid, the script stops and returns true....not sure why...I'm guessing I'm missing an "else" statement after the embedded "if" statement, but I'm only guessing and if I'm correct, I wouldn't know what to put in the else statement to let it not break out of the validation. Any input?

why I get an array containing [xml, xml]
Code:
str = 'index.xml'
re = RegExp( /([^s./]+)$/ ) ;
str.match(re) // -> [xml, xml]
I only need xml, not an array, and especially not [xml, xml]
Update: thnx mrhoo, thats clear now!

When I run the following code, the .Length function returns "undefined."
var strTest = 'test';
alert(strTest.Length);
Using the typeof function, I know that JS is treating the variable as a string.

I am trying to set a checkbox to true; but with no success, setting to false works. Here is the code;
$('#check:checked').attr('checked', false); // works great
$('#check:checked').attr('checked', true); // Does not work..
I also tried this
$('#check:checked').attr('checked', 'checked'); // also did not work
As a Sanity check i did this and it works fine .. document.getElementById("check").checked = true;

I have a question concerning :contains(). I use it in the following manner:
if($("div:contains('Built From')", $(itemProps)))
{
//Do stuff.
}
itemProps is DOM Element. It has a a div inside it which class is always something else however that div has either "Built From" or "Builds Into" as a text. Inside itemProps there is no other div with those words. I want to know which of those texts the div within itemProps contains. However this bit of code seems to always return true. Some goes for when I use the text "Builds Into". Even when the text is not in the div.

If "this" inside of a sortable "receive" function refers to the receiving object, How do I access the object to which the receive function belongs?
Example:
// Function that takes a JQ object and makes it sortable.
// We assign the "SortableRecieve" method to the receive event
MyObject.prototype.MakeSortable = function(JQOBJ){
JQOBJ.sortable({
receive: this.SortableRecieve
});}
MyObject.prototype.DoSomething = function(){
// Does something important
}
// The actual function that gets called when the receive event occurs
MyObject.prototype.SortableRecieve = function(event, ui){
// This function call won't work, because "this"
// doesn't point to the right thing!
this.DoSomething();
}
So how can I access the "True" this that refers to the object?

I have two grids, they both display buttons. One grid displays numbers, true or false and yes or no, and the other grid displays letters, true, false, yes and no.
The second grid is not displayed in the code (used css to not display second grid buttons (.answerBtns)) Now using the getButtons() function, if the user selects button "1" in first grid (the grid which you have to open using (Open Grid) link, then it should display button "A" in second grid, if user selects button "2" in first grid, then it should displays buttons "A" and "B" in second grid, if "3" then display "A", "B" and "C" and so on.
Now except using if statements and stating which buttons should be displayed and not displayed depending on the button chosen in first grid, is there a more efficent way of coding this so that the display of buttons in second grid depends on what is selected in the first grid?
If it is using an array can somebody show a sample of this in their answer. You can just do it for one example and then I should be able to use that to fill it for the other buttons.

I just found out that clone(true) and my masked input plugin aren'tplaying nice together.Inside of my plugin I grab a reference to eachobject like this: "var input=$(this);" and then inside of my boundfunctions, I reference "input". After a clone(true) the events thatfire on the cloned input act on original input.Does anyone have any suggestions/guidelines for how I can make myplugin behave correctly with clone(true)

I am using the below function to scroll to sections on a menu. It works but I need the links that activate the scrollto to still be links to pages. If I change "return false;" to "return true;" this links to the pages but the scrollto function does not work. Is there anyway it can do both?

I have a web app where I have created a div to masquerade at a textarea so I can add highlighting according to so rules. I rely on setting designmode=true. After certain amounts of idle time my code grabs the text from the div, which consists of tags and <span> tags and re-generates the html with new spans. The paragraphs and text stay the same. So far so good. But when the div "repaints" the insertion is set to the beginning of the div. I want it to visually stay put, meaning I need to somehow record where it was before nd then restore it afterwards. Problem is, I can't seem to get my head wrapped around how selections (Ranges, etc.) work. I've been googling around for the last day or so and have not yet seen the light.

I am using this Browser Plugin call: world = new MTSPlugin( '../obj/main.mtx', '100%', '100%', '', 'simple', ''); in the middle of my page, where I want to load this object. (It is a 3d rendering modul Viewpoint Player)
Now I want to add a browser check, as this plugin runs only in IE. When I dedect that the page is loaded with IE, I am writing via Jquery a class name into my body tag.
I thought, it would work if I do the following:
if($('body').attr('class').length > 1){
world = new MTSPlugin( '../obj/main.mtx', '100%', '100%', '', 'simple', '');
}
But for some reason, the if fails, as it seem that the plugin is called earlier than the jquery browser check, so the class name is not set at this point.
Then I thought, making a function arround and call it onLoad within the body tag.
Which has the disatvantage that the MTS Plugin is loading at the worng place on the page.
What I want, is that the call to the object "world = new MTSPlugin( '../obj/main.mtx', '100%', '100%', '', 'simple', '');"
is only at a trie condition at the place where it should be...
