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'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:
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?
I have a validate function that checks the form for blanks and all, also in the window.onload function I have one where it checks the format of the cc num and exp date. I am trying to get them to work together so that after I have entered the ccnum and ccexp it still makes me enter in the information needed for validate function. Right now after the ccnum and ccexp is entered it passes and submits.

I'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:
In the file script.js I got 2 functions: Code: function tooltip(){ var m=document.getElementsByTagName("A"); var k=[]; var mover = document.createAttribute("onMouseOver"); mover.nodeValue = "showtooltip()"; for (var i = 0; i<m.length; i++) { var mover = document.createAttribute("onMouseOver"); mover.nodeValue = "showtooltip()"; m[i].setAttributeNode(mover) }} This one is working. It's putting into <a href="#" title="some title" /> an attribute: onMouseOver with value: showtooltip()
And that's my 2nd function. Code: function showtooltip() { document.write(this.getAttribute("title")); }
When event is run the function isn't working. But when my html looks like this: Code: <a href="#" title="some title" onMouseOver="document.write(this.getAttribute("title"))">link</a> Everything is fine. And javascript console doesn't show any errors.
My 2nd problem is, that onMouseOver doesn't work in chrome (I got dev version). Even function like this: Code: showtooltip() { document.write("......"); }
I have a simple function defined on my page in the script section that should put me in a div named "apDiv4" a text when i press the down arrow in a text input called 'search2'. But it does nothing.
Here's the function:
And here is where i call it:
Why this doesn't work? I've tried onkeydown= "KeyCheck()" too.
I wrote a simple javascript function but I cant get it to work upon a button click event because it keeps telling me that "object is expected" ? could you please identify where the error is? Heres my code <html> <head> <title>Test</title> <script type="text/Javascript" language="Javascript"> function output(){ alert("Hello world"); } </script> <head> <body> <input type="button" name="btnSubmit" value="submit" onclick="output();" /> <input type=button onclick="output();"> </body> </html> It keeps indicating me that there is an error when calling the method on button click.
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 am new in jQuery. Actually in my application I want open a new tabs on every link. So that is done with following code. It is working fine. I have many textfields and buttons on every tab. So I want to disable those elements on tab loading
I want to fire onload event of body tag on click of a HTML button.Like if I click on the button the body's onload event will fire and a function called on onload event of body tag will execute.
Greetings!! I'm new in js..I've searched that js cannot perform two onload event at the same time. I've got two sets of codes here from [URL] and here is the the problem
i am trying to load/embed pdf inside a html object tag. since loadng of pdf content takes time, I want to capture onload complete event of object tag and take some action/msg to show usr that loading is complete. but i am not able to capture onload event of object tag. i get pdf content from an aspx page in bytestream and set it as data in object tag:
JS: function loadObjectsuccess() { alert('pdf has loaded now');
Talking about a js script which changes an iframe src through a "ref_to iframe.setAttribute("src", document_path);", I would like to launch a check() fct when this new document is loaded.
Of course, knowing, I don't want (and can't n some cases where document is generated by a cgi script) to edit every possible document which is potentially loadable in the iframe.
In fact, I've through about the idea to on fly add an "onload='check ()'" to every document, but don't know how to do that :-(
Maybe using attachEvent or something arounnd this : I don't know. Of course, I wish a solution working in the majors browsers.
I create two iframes dynamically to get data from the server. I want to deal with the data after it's downloaded, so I set the two iframes' onload event handlers to current document(not the iframe self), the handlers' JS code is generated dynamically too.
But I found only the second event is triggered and I can't get the first iframe's onload event.
Why? The data in the first iframe is really arrived, but it doesn't trigger the onload event.
Is there any other better way to conceal download data from server, not refresh current document?
I've got this very simple jquery script for creating a sticky footer below: $().ready(function() {
[Code]...
This works just fine in most circumstances. However, i'm noticing one significant bug. Lets say I have my website autosaved to a tab. I start the browser and the website automatically loads. When this occurs the above script does not work.Instead the footer appears a 1/3 up the page behind the main content. After the page loads incorrectly if I refresh the browser it then loads properly. All future pages in this browser session will then be ok. Its just the first time the webpage loads when I start-up my browser that I experience this bug.
Firefox - Occurs everytime browser loads IE - Occurs when browser loads if cache has been reset
If I use a window opener to open a new window, is there a way to detect that the new window is finished loading before carrying out some other directive in the opener window? Can I access the remote window's onload event from the opener window? I need to know that the website has loaded before moving to the next page. something like:
Been trying to get a short script I wrote to work 100%. Basically it checks to see if the main page image is =>375px and if it is shunts the text down below it. Its not a live site yet and due to it being so short I thought I would just copy and paste it here:
function checkImage(imageId) { if(document.getElementById) { var id = document.getElementById(imageId);
[code]....
The problem is with IE6, it randomly decides not to work without any sign from the debugger that anything is wrong. This is my first time using onLoad with an image, is there any quirks with it such as page load order (e.g. if the image finishes loading before the text loads this wouldn't appear to run?).
I'm having a problem on a site where an onload event works in Firefox but not in IE. Actually, the onload event works in IE once - but then if the Ajax onreadystatechange changes, IE chokes and doesn't use the onsubmit event that worked when the page first loaded. Code:
Try entering something that isn't an email address and submitting it. Then try just submitting a blank form. Firefox will do the asynchronous call to a PHP script and return the results - IE will do it the first time, and then not again. Code:
IE works fine if I add a simple 'onsubmit="saveData();"' to the form itself, but I'm trying to keep my semantic, presentation, and behavioural layers separate. Using the DOM seems to be the way to do that, but IE seems to only do an XMLHttpRequest once and then stop listening for the event.
