I'm trying to assign and event to a tag during the onload function,but I don't seem to be using the correct syntax.

[code].....
I'm trying to convert an on load event into a function. I think this should be really simple, but I'm new to Javascript. The following works fine as the page loads
var favorite = GetCookie('DemoName');
if (favorite > Ƈ')
{
window.location.href = 'page2.htm'
}
else
{
alert('You must complete the lesson before proceeding');
}
I have tried to make it into a function by adding function CookieRedirect() {
at the top and a closing
} at the end, and calling it using a form button in the body:
<INPUT TYPE="button" VALUE="Redirect" onClick="CookieRedirect ()">-
but no luck.
I've been developing an application that uses a combination of Javascript and PHP. It's a sizeable form that includes the option for the user, on certain form objects, to add additional text boxes for multiple answers. I created a Javascript function that uses the insertRow() method. The user can click on a link which adds a row with a text box for an additional response. My function works great and, after some work around I got the values to post correctly, but where I'm running into trouble is re-populating those additional fields if I have to bring the user back to edit input that was not put in correctly.
My solution was to have create a PHP varible which is a javascript function call, e.g.:
$var = "js_function('varName1','varName2', 'varName3', 1 , '" . $post_val . "')";
Using the posted variables that apply and then echoing that into the onload event handler in the body tag. This calls the same function that was originally used to add the row to have it add the row again and populate it with the already submitted data. It all looks great, like it should work, but it doesn't and I'm wondering if there is something about the onload event handler which I don't know about. It was my understanding that the event handler executes when the page is fully loaded. If that is the case, my solution should work.
I don't know if there's some error I'm not seeing or if I'm trying to make the onload event handler do something it's not supposed to. I used a similar solution on another application and it works there. To give a better understanding, here is the function:
function appendIaRow(tblId, valID, oName, Nbr, populate1, populate2) {
var tbl = document.getElementById(tblId);
var newRow = tbl.insertRow(tbl.rows.length);
var numi = document.getElementById(valID);
var num = (document.getElementById(valID).value -1)+ 2;
numi.value = num;
var rowID = 'Row'+num;
newRow.setAttribute('id',rowID);
var newCell = newRow.insertCell(0);
newCell.innerHTML = "<input type=\"text\" name=\""+oName+"Name["+num+"]\" value=\""+populate1+"\" size=\"20\" maxlength=\"150\"/> <a href=\"Javascript:;\" onclick=\"deleteLastRow('"+tblId+"','"+rowID+"');\" style=\"text-decoration:none\">X</a><br /><br />";
var newCell2 = newRow.insertCell(1);
if (Nbr == 1){
newCell2.innerHTML = "";
}else{
newCell2.innerHTML = "# <input type=\"text\" name=\""+oName+"Number["+num+"]\" value=\""+populate2+"\" size=\"17\" maxlength=\"17\"/><br /><br />";
}}
Here is the coding for the event handler('initialize()' is a different function altogether - that works):
<body onload="initialize(),<?php echo $init ?>;">
And here is what it looks like from the source code when the page is displaying in a browser:
<body onload="initialize(),appendIaRow('AdmTbl','AdmValue','Administrator', 1, 'Joan'),;">
I am having issues with the following bit of code:
function test(){
window.alert("Alert1");
var testvar = document.getElementById("topMenu").getElementsByTagName("li");

I have the following javascript function:
[ function addNewWindowEvent(evType, fn)
{
if (window.addEventListener)
[code]....
How do I pass a PHP variable into a window.onload event function? I have a URL that I need to pass to the JavaScript file that has this function in it. The JavaScript file itself is being linked from the PHP file that will pass the variable and I've seen many examples of how this is done via embedded JavaScript, but none where someone is linking to an external JavaScript file. I suppose this is probably a trivial matter to most of you, but I've never done this before and could use some guidance!

i have an html page that when it loads theres an onLoad event called which calls a function.now what i want to do is be able to click a link that refreshes the page but at the time on the refresh it skips the onLoad event. is this possible?
View 5 Replies View RelatedI'm having a hard time figuring out why the onload event is not being
called for the frameset window in the following simple example. It is
being called for each of the component frames. Code:
I am wondering why the following works, on IE6, but with an error : "Not
implemented".
function TEST(){}
TEST.prototype.Initialize = function()
{
var mImage = new Image();
var mDate = new Date();
var start = mDate.getTime();
mImage.onload = this.Alerting(start);//WORKS with ERROR "Not implemented"
//mImage.onload = function(){this.Alerting(start);}//ERROR "Object doesn't
support this property or method"
mImage.src = "winxp.gif";
}
TEST.prototype.Alerting = function(i_string){alert(i_string);}
var mTest = new TEST();
mTest.Initialize();
Can anybody guess why?
I have written a script that gets trigered by IE's toolbar button. In
this script I would like to asign an event handler to an element of the
document currently open in IE. The way one access the document object
from a toolbar button script is:
var doc = external.menuArguments.document;
Now assuming the document has an element called TextArea1, the logical
thing to do would be:
parentwin.document.all('TextArea1').onkeypress = new
Function('window.alert('asdf');');
Which goes compiles and runs, except the event handler does not get
triggered.
Another trick i tried is as follows:
var s = parentwin.document.createElement('script');
s.text = 'window.alert('asdf')'
s.htmlFor = 'TextArea1'
s.event = 'onclick'
parentwin.document.scripts[0] = s;
Same result.
Hi have an event called function allownumberonly(evt);
My html text input onkeypress calls this function.
onkeypress=allownumberonly(event)
I want to create a text input dynamically and set its onkeypress event
to the above function also passing the event.
I'm having troubles assigning an onclick event to a cell. Im trying
something like:
cursorPoint.cells[3].style.cursor = "hand";
cursorPoint.cells[3].width = "20";
cursorPoint.cells[3].onclick = "alert('this is a test');"
cursorPoint.cells[3].alt = "Select the columns";
cursorPoint.cells[3].innerHTML = " "
Everything is just working fine except the onclick. I also tried:
cursorPoint.cells[3].click = "alert('this is a test');" (without the
"on") but also didnt work.
I was wondering if anyone knew if/how to assign an event to
a global variable?
I tried to do it and IE 7 came back with an error saying "Member not
found"
My code looked similar to the following:
var globalEvevnt;
function showPopup(event){
globalEvent = event;
alert(globalEvent.type);
setTimeout(function(){unhideDiv()}, 2000 );
}
function unhideDiv(){
alert(globalEvent.type); //Member not found error found on this
line
}
I was wondering if I had declared the globalEvent = new Object();
would that make any difference? I thought everything in JS was an
object so the event could be stored to one as well?
I have this code where we initialize the themeswitcher
[Code]....
where themeSwitcherSelect is my function, but it doesn't work. What am I doing wrong?
What I am coding now is a piece of a much larger project that I am, for the moment, developing on my own. This code, relatively useless on its own, is essentially practice or proof -of-concept. Much of it will probably be used in the larger project. If at times, it seems that I am using a cannon to kill a fly, this is why.
Additionally, I do not claim credit for all the code here. Some of it is copied from other sources. I have studied it, understood it , then modified it appropriately, making it my own.
However, the code is broken. I have tested it on Internet Explorer 9.0.??? and Firefox 4.0.1. It breaks in both browsers. I have previously tested it in Chrome, but not recently. On IE I have used the built in debugger, and I have been using Firebug in Firefox. I have also used the debugger at [URL] quite frequently. JSLINT returns some 'Bad Type' errors regarding 12 lines in the html body, each having the structure: <td><input /></td>. I can find no explanation for the 'Bad Type' errors. Otherwise, according to JSLINT, the code is fine.
The predecessor to this code worked fine. I had been using inline event handlers (onblur and oninput) that called the doMath function when one enters data into the table. The values are then averaged and summed. All this is extremely basic. The problem began when I removed the inline event handlers and began to use window.onload (I believe I am using document.onload now, but the problem has not changed.)
I have adopted Douglas Crockford's 'walkTheDom' recursive function to find all tags with a particular class name. I would like to assign every element in the array returned by this function an event handler.
This is the problem: This script simply cannot find the body node of the DOM ( and, seemingly, none of its child nodes either). Initially I tried 'document.body', which failed. I then began with 'this' (essentially 'document') and tried walking the DOM to get to it ('body') eventually. This, too, failed. I tried array index notation to refer to it(I forget the specific syntax), and most recently, I've given it ('body') an id and referred to it directly using 'document.getElementById()'. These most recent attempts also failed.
After hours of figuratively bashing my head against the wall looking at code and probably even more time doing research online, I am extremely frustrated. As often seems to be the case, my problem is probably simple
I have included most of the code, even though it is a little long. This way you may easily copy the code and reproduce the problem yourself. I do not often post to forums, and, more relevant, I have no idea where the error may be located.
Potential problem areas are in RED.

Trying to create a date validation form; since most don't do what I need. So far it's doing ok; I'll admit I found a lot of the code on the web, but I wanted to add it where it would automaticly change the string entered (Example if a user did 3/5/2010, it would make it 03/05/2010). Well getting the month was easy, however I'm having trouble fixing the date. Here is the problem section. ValDate is called from the validation function.

Is there a way to have a script fire on page load other than using the
"Onload" in the body tag ?
Want to know is is possible to have 2 diff. onload events in the same page? I have 2 different scripts for 2 diff. things. They both use onload event.....if so, how can we handle it.

I'm pretty new to Jquery but been using mootools for quite some time now... I just wonder, how could I assign function to jquery? In javascript, we do the regular :
function Myclass() {
//some code here
}
and call the Myclass by:
Myclass();
In mootools:
var Myclass = new Class({
//some code here
});
And call the Myclass by:
window.addEvent("domready", function() {
new Myclass();
});
In Jquery, how would I do that? Is it okay to use the javscript function instead? Or is there a standard way of doing that in jquery?
function Myclass() {
//some code here
}
$(document).ready(function() {
Myclass();
});
