I'm using javascript to dynamically make controls show up or disappear on a form. For some reason, if I load a control (in this case a select control) into the Div it shows up perfectly. If I load text in there, it is fine too. However, if I programmatically try to go from the select control content and cover it with text afterwards, that won't work.
If I change the content from one string to another, it works as well. I just cannot remove a control I've put down and replace it with text or "" or whatever.
While I am an amateur beginner when it comes to JavaScript, I feel that I can at least handle the scripting language to a level which suits my needs, however earlier today a friend asked me if I could lead her to the right direction with a class task of hers. Basically, the project at hand is to create a snippet of JavaScript which, when the user clicks the content of an HTML paragraph element, should replace said paragraph with a <textarea> and allow the user to alter the paragraph's content. Of course the textarea should be accompanied by a save and a cancel button, but seeing as it is a JavaScript class she's taking, the saving shall only be client-sided.
However, the catch is that she will not be allowed to use the innerHTML property.
So, to the question: how would one go (if it is possible, but I highly doubt it isn't) with making something like:
I do feel this could be done in a more smooth looking and operating way by using the contentEditable attribute, but apparently the teacher asked for a textarea.
I am working with Netscape 7.0 and need to bind a <divwith the innerHTML property. More specifically, I need to bind a GridView in the div in question. I am binding the div with some hardcoded data (a table, which is the HTML equivalent of a GridView). Is there a way with javascript to dump the memory used by a DOM object (the div that I am binding with innerHTML)? When i just receive the variable in javascript, it doesnt seem to leak. I have tried removing and adding the div each time I bind to it, but it still leaks.
Is there a way to add an if and else with in innerHTML like this. var sfe = document.getElementById("mainform").innerHTML ='<form name="'+frmName+'">'+ '<!-- comment -->'+ '<h2 id="pa" name="dr">';if(n == 1){'+fname+'}else if(n == 2){<b>No Title</b>} '</h2>'+ 'more'+
I am getting data from two tables in a database using a dropdown box with a onchange and some ajax to update two diferent Div tags, basically the id is passed to a php page,, I grab the data from the two tables, I then echo the data in two html tables. I echo a ** for a delimiter between the two tables,
Then I use a javascript split function to split the responseText into two peices so I can update each DIV with the coresponding data.
Everything works in Firefox, but in IE7 only one div gets updated with its data, the other div will not change, and I get a unknown runtime error. However if I go into my php page and change the data I am echoing after the delimiter to a simple echo 'test' it will work. Code:
I've got this code that creates a new new row and cell. I then put some text into the cell with innerHTML - works beautifully with Firefox but fails with IE. I guess IE doesn't support this way of doing it, but is there another way of doing it with DOM?
Here is my problem in a nutshell: a script to model dynamic table extension. It works under Firefox. But IE just aborts, complaining about an "unknown runtime error" in the line with "innerHTML". Why?
<html><head></head><body>
<script language="javascript"> function extend() { var tb = document.getElementById('thetable').tBodies[0]; var newrow = document.createElement('tr'); tb.insertBefore(newrow,tb.rows[tb.rows.length-1]); tb.rows[tb.rows.length-2].innerHTML = '<td>A</td><td>dummy</td><td>row</td>' } </script>
Why doesn't a SELECT element's innerHTML reflected which option was selected? Works in IE. I need this functionality so that I can retain what choices a user made in a tabbed interface.

I want to load an external file into my page via XMLhttpRequest and innerHTML. The external file contains javascript code which is not executed during or after insertion. All the HTML markup is displayed just fine.... basicly even this code doesnt work:
var img = document.createElement("img"); img.attachEvent("onclick",alert("test")); var div = document.createElement("div"); div.appendChild(img); //can't work; div.innerHTML="<-click this";
but i use attachEvent like this,it work; eg:
var img = document.createElement("img"); img.attachEvent("onclick",alert("test")); var text = document.createElement("span"); text.innerHTML="<-click this"; var div = documet.createElement("div");
div.appendChild(img); //can work div.appendChild(text);
How can I get the innerHTML of a <div> area only when the page loads, then use that variable in a function?
Here is my code: function setContent(zz) { var lb = document.getElementById('leftbar').innerHTML; var rb = document.getElementById('rightbar').innerHTML; document.getElementById("myContent").innerHTML = "<span class="title_Page">"+Page[zz]+"</span>"; if (zz=="home") { document.getElementById('leftbar').innerHTML = lb; document.getElementById('rightbar').innerHTML = rb; document.getElementById('leftbar').style.width = 食px' document.getElementById('rightbar').style.width = 食px' } else { document.getElementById('leftbar').innerHTML = ""; document.getElementById('rightbar').innerHTML = ""; document.getElementById('leftbar').style.width = Ɔpx' document.getElementById('rightbar').style.width = Ɔpx' } }
I want lb and rb to be set only once (i.e. only when the page loads the first time). I tried putting those variables outside the function, but when I do they, they show up as undefined. So how could i code it so that when the page loads, it assigns the innerHTML to the two variables, but not any other time while that page is open?
Can somebody explain why this happens, and how I can solve it? Since the first case works on all browsers I tried, I was hoping to get a browser-independant method to read the sourcecode of another file. By the way, all files are local.
I'm using an i-frame to grab a server-side text file and display its content elsewhere in the html document. On change of the i-frame source, I want to access its innerHTML.
The i-frame source changes just fine and even displays the source; the glitch is in accessing the innerHTML for that new i-frame src file. It requires *TWO* clicks of the onClick element to get the correct innerHTML (with just one click, the source will change, and display the new file in the html document; however, the innerHTML is still that of the old source file for the i-frame).
This does not appear to be a loading problem with the new src file into the i-frame. (ie: setTimeout on a function to get the innerHTML after the src file loads does not work).
So the question is: how can I get the i-frame source to change AND access the new src file's innerHTML with one click?? Code:
so I have this code for a date form and I made a PHP loop and even a javascript loop for it. There is a script that supposedly adds multiple 'dates' when the user clicks this 'add more date' button and I use an innerHTML to clone it.
My problem is how will I put it inside an innerHTML on a javascript. Since innerHTML reads html tags, is it possible to put a PHP loop within it? and how will you also call a javascript function within it?
this is the PHP code: <select> <?php for ($i=date("Y"); $i>=1950; $i--)
[Code]....
I just need to know if what im doing is right, or is there another way to do this?
I'm working on a script that inserts things into tables. It's complicated and involves xmlhttp and lots of stuff, but I've narrowed the problem down to something simple. The following code does not work in IE. It doesn't generate an error, but simply displays nothing. Here is the code:
I'm trying to hide a TR if a TD within it has only specific html in it. Why would this not work: if(document.getElementById('website1').innerHTML.toLowerCase()=="<a href='' title=''></a>") { document.getElementById('website-row').style.display='none'; }
I'm sending arrays of results from my server in response to an xmlhttprequest like so:
array({key:value[,...]}[,...]);
I know I could use an associative or indexed array, but this is just how I wrote it as I'm using the prototype library and I'm in the habit. Anyway, I want to know if I can reference 'key'. If so, umm, how?
I am nOOb to Javascript and wanted to extract HTML from another website. I tried this by using an iframe that opened up the desired webpage and called a script to read the innerhtml of the frame using the onLoad event.
It fails however with a Permission Denied error when trying to extract the html via the script (see code below).
Not sure if I am doing something worng, or if this is just not allowed on ClientSide scripting (I can appreciate writing isn't) but not being able to read.
Anyway, assuming this can't be done in this manner, is there another way in which it might short of using server side scripting?
<SCRIPT language = "Javascript"> function readFile() { doc=window["myframe"].document.body.innerHTML; //TBD...
