I have just started learning JQuery and have a doubt in the below code. $.get('myhtmlpage.html', myCallBack);The doubt is should the 1st parameter of the get function be a HTML file or can it be a unction name?

View 2 Replies View RelatedI want to change the elements class name dynamically when mouse is out with respect to that element.I want to change the class name after some delay (i.e, i am using settimeout function).
var ulNodes = getElementsByClass("nice-menu");
var liNodes = null;
for(var i = 0; i < ulNodes.length; i++) {
liNodes = ulNodes[i].getElementsByTagName("li");
for(j = 0; j < liNodes.length; j++) {
if(liNodes[j].className == "menuparent") {
liNodes[j].onmouseout=function(){
timer = window.setTimeout(function (){
this.className = "menuparent"; //My problem is with //this line
},4000);
} } } }
I need to set the elemets class name to "menuparent" after some delay after the pointer moves away form that element.
-> When ever i say alert(this.className); in the setTimeout function, the alert box says undefined.
-> I can succesfully alert any where else in the mouseout function except within the settimeout function in mouseover function of that element.
Captions for the images are called from the parameters of the main function and delivered into a span or div tag with the appropriate id. A very important part of what needs to be in the captions is text compiled by a separate function, in the project library.I've tried this with and without curly, square and round brackets, with and without semicolons and quotes- all with varying results. Sometimes the function is called, but it appears at the very top of the page and nowhere near the proper <span> tag.
addImage(a,b,c,d);
// filename, image name and caption are in a, b and c.
// d is the variable where I need to write my other function...
addRef(t,s);
// I need to put addRef in the d parameter of addImage.
Is there any way to pass a function(with its parameters) to another function using a parameter?
Examples:Here is how I do it now:
function output(text){
alert(text);
}
function bla(text, func){

I am trying to use a regEx to grab Function names and function parameter names from a text entry.
The script is written in javascript and I expect the functions to be in javascript syntax.
For example the code might look like:
Code:
function myFunction1(param1,param2,param3){
some code
}
function myFunction2();
function myFunction3(param);
Whats the best way to accomplish grabbing the function names and parameters?
Should I be breaking it down into multiple regular expressions?

I'm not exactly sure why this doesn't work. I'm basically just trying a
simple approach at a slide down div.
function slide_div {
setTimeout("document.getElementById('mydiv').style.length=ཆp x'",1000);
setTimeout("document.getElementById('mydiv').style.length=ཐp x'",1000);
setTimeout("document.getElementById('mydiv').style.length=ཚp x'",1000);
setTimeout("document.getElementById('mydiv').style.length=ཤp x'",1000);
setTimeout("document.getElementById('mydiv').style.length=p x'",1000);
setTimeout("document.getElementById('mydiv').style.length=ླྀp x'",1000);
}
It seems like it just runs the last setTimeout line and pops out all at
once. I've even tried adding a=, b=, c=,. etc at the begining of each
line to no avail.
does anyone know if the setTimeout() function in js has been just recently supported? i created an online demonstration of a product that uses this function to delay the playing of .wav files after various second intervals. i know that Opera doesn't support this function because when I click my button, all of the .wav files that i have in the function that runs behind the button play at once. i have probably 10 wav files that are played throughout the function, at various conditional statements. does anyone know if earlier (like REALLY old) versions of IE do not support this function? or maybe ie8 doesn't support it? i developed this and tested it in all major browsers except IE8 and any version earlier than IE6.

I did search the forums but couldn't seem to find anything on this specifically. I basically need to pass a key event and a 'name' to nameCheck() after 3 seconds. This works fine in Firefox but Internet Explorer gives the error: Member not found. I'm more of a PHP guy than a JS one
<input type="text" onkeyup="nameCheckTimer(this.value, event)" value="" />
function nameCheckTimer(name, evt) {
setTimeout(function(){return nameCheck(name,evt)}, 3000);
}
function nameCheck(name, evt) {
//need name and the key event to be available here. I have code to handle the key codes which works fine
}
I am trying to use the window.setTimeout feature so that a message pop-up with yes/no appears on the screen asking whether to extend the session.*If yes is clicked, the current page reloads.*If no is clicked, nothing happens. (the session will expire anyway).
View 5 Replies View RelatedI have written the following code (quite meaningless. Just to check why setTimeout is not working in a similar real-life code) to enable the user to input a given time interval (hh:mm:ss) when a p is clicked, and then alerting the user with the time entered in the seconds portion one second after the div is clicked. But it is not working. I think the setTimeout is the culprit, the way I am passing parameters to the function inside it, but don't know where exactly am I erring.

I have a button that when you click it displays the results of my db in a div. What I am trying to do is to get the results to update every five seconds.
I thought setTimeout was the best way to achieve this. However I am getting the error message that ID is not defined on the setTimeout line. I thought it would automatically input ID into the fields marked ID when the onloadXMLDocRefres ('File.php','txtHint') button is clicked?
The button works to load the script, but the refreshing the div is not.code...
I wanted to write my own script for a fade-in animation, since the ones I have found have got too many options or need some framework, which makes them unnecessarily big. I wanted to learn too.Unfortunately, the code didn't work as I wanted, and I commented some things so as to find out what's happening.Why is an object reference assigned to what was previously a string?
View 6 Replies View RelatedI'm trying to graph line with a delay between each line drawn - my code is:
var jg = new jsGraphics('Canvas');
jg.setColor('maroon');
jg.drawLine(40,130,80,120);
setTimeout('jg.paint()',10000);
jg.drawLine(80,120,120,110);
setTimeout('jg.paint()',10000);
Unfortunately it draws all the lines at the same time i.e the setTimeout function doesn't like the paint method.
I'm new to JavaScript, and have been playing around with a few simple functions to get going. However, I've hit a problem that I just can't fix, I'm trying to write a simple function to animate the collapse of a div using setTimeout (I know, jQuery does it a lot better), and it's gotten the best of me. The only error it's giving me now is
Code: missing ; before statement on line 25 but I can't see why. I assume it's something to do with my abuse of the setTimeout syntax (why does it insist that everthing is enclosed in quotes.I'm sure there are much better scripts than mine, and searching the forum I've come across Vic Phillips' fine specimen which mostly went over my head. But if I just wanted it to work I'd use jQuery - I'm more interested in why it's not working.
code is below. In addition to this I've also got an external script to compensate for browsers without getElementsByClass, but it should work in modern browsers up to the point where it doesn't!

I have a simple JS function that I want to return a true or false value
based on the parameter passed in. At this point of time I receive the
error "'True' is undefined". Here is my code below.
JS Function -
function ShowSpecifiedPeriod(pShowPeriod){
document.mfperformance.ShowPeriod.value = pShowPeriod
document.mfperformance.method = 'get'
document.mfperformance.action = 'composite_requestdata.asp'
document.mfperformance.submit();
}
ASP Event Handler -
onclick="ShowSpecifiedPeriod(<%If bShowPeriod = false then
Response.Write true else Response.Write false%>)"
The ASP variable bShowPeriod is set based on the hidden form field
"ShowPeriod" and the initial value is set to false.
More than likely this has to do with the boolean Parameter but I am not
sure how to handle this in JS. I have tried the following but receive
the same results.
function ShowSpecifiedPeriod(boolean pShowPeriod) - Same Error
function ShowSpecifiedPeriod(pShowPeriod boolean) - Same Error
Please let me know what I am doing wrong here.
I have an XML string which I want to pass to a java script function, where I am displaying that in different window with use of 'window.open()' method, but it is giving error.

I'm adding buttons to my google map through a loop. I pass some parameters, and the addButtons() function creates the buttons. How can I pass the "task" for the button to the function? In the addDomListener line below, I'm now writing the function name literally, I'd like find a way with a parameter.

I have a JSON array data.cells that I need to iterate through to get the values out of and put the values into an onclick event listener.
Right now the variable name data.cells[i].letter is being based through the buildString function for each cell in my board, instead of the value of the variable. Same goes for the x and y variables.
I've been searching now for quite a while trying to look for a way to give the default value to a function argument if it's not given. For example, in php one would do the follow:
function func_name(foo = 'default') {
...
}
In the above case, if foo isn't supplied while calling for the function, then foo would default to 'default'. I have tried that in javascript, but it doesn't appear to be working, so I am wondering how should I do this in javascript?
I have a js file which will open a web site.
Code:
function openurl(url)

The argument url will be from an input field in a html file.How to implement it?
this works:
document.all[sResponseDivID].style.visibility = 'hidden'
this doesn't
setTimeout("document.all[sResponseDivID].style.visibility = 'hidden'",1000);
looks like sResponseDivID isn't recognized. what's the problem?
