Image Changing And Changing InnerHTML With JS : Query
Jul 6, 2011
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 ?
So im using this framework called CodeIgniter anyways it allows query strings but by default I have turned them off. Instead a url would look like this: [URL] However jQuery or the plugin datatables that I am using is generating it like this: [URL] Just trying to figure out where all this magic happens so I can change it to my magic!
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");
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?
I found this slide show [URL]. I got it to work on my website [URL] using Firefox, but when it is viewed in Internet Explorer it will not work. Second question, When the slide show gets to the last image, after the last image all photos disappear and it resets itself changing the format of the webpage. Any way to not have the images disappear while it loops itself or is there a code to have it stop on the last photo and not loop.
I've made a gallery that has thumbnails along the top and clicking them changes the source for the full size image below, but it seems I can't change the image size.
A workaround I made up is to put the fullsize image tag inside a div tag. Clicking a thumbnail changes the innerHTML of the div to an image tag with the proper size and source.
I'm wondering if this is the way to do it or if there's a better, more proper way?
ok, I am just learning this stuff, small stupid question here...I am trying to swap images in a little ajax application, and the code handling that looks like...
document.placeholder.src =xmlHttp.responseText
/ no big deal i know, if i print xmlHttp.responseText to the screen the link is correct, but anytime I assign it as a src, i get the link+(all the page html attached on the end) and i dont know why?
I am trying to write a script to display pictures. I have the following code which works OK for displaying the next or prior picture. I know there are plenty of scripts out there for this, but I want to do it myself. So, I'll worry about the pause/play later. I dont know how to write the image using javascript. My problem that I currently want to fix is the first picture displayed is not initialized; that is, the variable I guess. I am passing the directory name, which is this first function. So, I have to click NEXT or BACK (my buttons) to display the first picture (actually the 2nd)... Code:
I've set up a few images to change onlick using the following code (I have the alternate images saved as jpgs in the img/ directory). There are two problems I'm having the first baffles me, after clicking one image and changing it the other images take 2 clicks before changing. The other problem is more of a curiosity, I plan to have these images work as a sort of check box for a sql database query and I'm not entirely sure my current way of doing it will allow for that.
Code: <body> <head> <script language="JavaScript" type="text/JavaScript"> var q=0;
I have a mapped image and I want to change mapped parts of the image. For example when I get a cursor over one area the image in that area would change for another (the same size of course). Or for example I have mapped solar system and after clicking one of the planet the planet will change color (so the image will be switched just in that area).
