Code:
function toggleVisiblity()
{
var name1="eg";
var tbl = document.getElementById("chart1");alert(tbl);alert(tbl.style.display);
alert(tbl.nodeName);var clink=document.getElementById("chartlink");
Ive got a small image of a power button and when pressed the inner section on the button changes to yellow, but when its pressed down Im also trying to get part of my H1 (main header logo title) to change to yellow.
Ive created a span with an id surrounding the letters of the H1 that I want to change, the id being : "power";
The javascript that I have come up with so far and works is as follows:
<img id="poweron" src="http://www.sitepoint.com/forums/images/power.png" alt="Power on button" onmousedown="this.src='images/poweron.png';" onmouseup="this.src='images/power.png';"/>
I understand Im not really supposed to be using inline JS, and I know Ive got to create a function for the onmousedown event to trigger changing the H1 text, so am I under the right impression that the JS so far written is redundant and will have to be re-written so thats contained within a script placed just before the closing </body> and an external script for invoking the main function ?
Isn't that weird? Because text_val is assigned the value of innerHtml. So if text_val is shown to be 50 then why is innerHtml shows value as 5? The div always shows 5 seconds.
I am trying to create a button that when pressed changes not only the value of the button but the onclick event. I basically need the function to toggle between these two functions but I can't get it to work. The button changes value but will not update with the new onclick value.
I am currently making a website with 2 Frames, top and bottom. Top Frame will be a table.Bottom Frame will be a row with the information from the last row *you* clicked in Top Frame.
I created a page that has an iframe on it. Within this iframe I call an asp page. The asp page is supposed to do some work and then update the innerHTML of a <div> object on the parent page to indicate that processing of the page in the iframe is complete. The code works in IE but not FireFox. I am wondering what is the best way to make the script work for both browsers?
I was playing around with some onmouseover/onmouseout and setting innerHTML to various strings depending on what has been mousedover/out. The DIV for the innerHTML was above the items being onmouseovered/out and because the strings sent were of different lengths, sometimes a one or two line wrap would happen and everything below it would be resized accordingly creating a horrible effect. For reference, what is a good way to approach building pages which are immune to this effect?
I am trying to change the font color of each character of the innerHTML of a div. I have tried the following but obviously I have not gotten it to work.
This is just a snapshot of the javascript which I have that "changes the color and size of the characters..
Code:
function change() { var r = 0; var len = document.getElementById("userInput").value.length;
I'm populating a table from my database using .Net and within this application, I am then comparing the value the user has entered to the first column of every table row in the pre-populated table.For some reason, when I loop through each row in the table and return the value in the first column...the value always stays the same when in fact i know its different by just looking at it on the screen and in the html source.I throw up an alert message for each time it loops, and it its looping the correct amount of times, just not returning a the correct value.
I have this partially achieved when clicked, any number will indeed "turn into" an h1'd representation of itself but I can't get the other links in the group to disappear when the h1'd number appears (onclick).
I currently have a normal link like Code:<a href="http://sitepoint.com" class="link">sitepoint</a> and when a user clicks on it I want to be able to change the "link" class to a different class. However, I don't want to add anything to the actual link html. Is it possible to do this using javascript without modifying the original link code?
I am trying to dynamically clear the value of a form input field and then submit the form.When I used $('#my_field').val('') to clear the field, it was cleared on the screen but when the form was submitted the original value of the input field was posted.My browser is FireFox and I can see using FireBug that when the field is cleared, firebug is still showing the html code with the old value. E.G. <input type="text" value="old_value" />The same situation occurred if I used $('#my_field').attr('value', '') to clear the field.The same situation occurred if I actually changed the value of the field rather than just clearing it.To work around this problem I ended up using the $('#my_field').removeAttr('value') to clear the field before it was submitted.
I am a complete novice when it come to Javascript. I copied the script for displaying random images at a specific interval (from javascriptkit.com). I would appreciate knowing whether the following is possible:
The pages are based on tables, so the parts that change are all cells.
1. Can I define text instead of an image in the array? i.e. can I have the image change to say an apple in one cell and the next cell have text explaining what an apple is?
2. Would it be possible to put a countdown timer for when the image/text is going to change?
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);
