i'm new to jquery and am not real familiar with javascript. I have a color picker on my page that puts the hex value in an input box. I'm not familiar with jquery or javascript in general. I would like to be able to take the hex value and use it in updating a style of a div onkeyup or onchange...say the border color for example. Something like this...but this isn't working.
OK, been banging my head with this for a while. I have a dynamic sitewhere we get a list of elements from the database, we identify theseitems with id numbers and encoded get strings. So I'm trying to getstyle changes to take affect with jquery and it really just doesn'twork.I'm not sure what I'm doing wrong. Here is the source code:
How do I check the status of a style? I thought something like this would work, but no joy:divTest = document.getElementById('link_container'); if (document.divTest.style.display == "none") {}
This does not work. Not sure what I am missing. Basically I want to toggle the none/block value in the style on the span class below based on the browser detection script.
I am building a schedule web page and before I just had it use plain static HTML and CSS to control the styling. I wrote some javascript that goes through the table's rows, then cells (double for loop), and if the cells innerHTML == "" then the style class is changed. I do have some working code, however it only works in IE. Here's a copy of the script:
<script type="text/javascript"> for (var i = 0; i < document.getElementById('table').rows.length; i ++) for (var j = 0; j < document.getElementById('table').rows(i).cells.length; j ++) if (document.getElementById('table').rows(i).cells(j).innerHTML == "")
I am trying to get the color of the list item 'SUBJECTS' to turn red on mouse over. I think my syntax must be wrong but I don't know how so. What can I do to fix it?
I am attempting to change the style after the user has loaded the page(every x number of seconds) but the element just doesn't seem to berefreshing. I have done all of the checking, and it seems like it ischanging it but it isn't showing that on the page.
I'm currently putting javascript function onto a page to swap the content between 2 divs onclick- when one is visible one is hidden and vice versa (they are in the same place to create a tabbed browsing effect).
the script:
<script type="text/javascript"> * function detailStyle() {
How to change style on a series of divs (with similar structure but different content) *only if* all the children are visible (that's using visibility, not display). Sample div: <div class="h"> <p class="a1">text</p> <p class="b2">more text></p> <p class="b3">text text</p> <p class="a4">text...</p> <p class="link_display_none_visibility_visible">div name</p></div> I think it needs to use contents(), but not sure about handling node numbers.
I change image.style.width inside a image.onload function. And surprisingly, I found that it runs the onload function on the same image again with the new style.width value. Javascript treats this as a new image! This is the same old image.
Is there a way to pervent it from runing onload the second time?
My understanding had been that $.css("width") would return the original user selected style, eg "100%" or "10em", and $.width() returned the computed width, always in "px". Not so, following the code through for .css(), it calls something called getComputedStyle and the only difference between the two functions turns out to be a post-fix of "px" on the .css() result - not very useful. I need to know whether my user has called me with a proportional dimension, or a fixed one. How to tell with jQuery?
This is probably quite a simple problem but I can't figure out the answer. I'm working on a site that has news stories and events coming in. What I would like is to have the news stories to be styled with squares and events with discs for instance. I might be able to change the actual plug-in so the CSS affects this change, but I just wondered how I could change the list-style-type with jQuery.
if I have an html page that uses the <style> or a <link> to call a style sheet these properties aren't available to JavaScript is there a good way to access them? eg
<html> <head> <title>expandable text area</title> <style type="text/css">
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?
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 ?
I found that if I define the style(visibility...) of a Div in a CSS class, I wouldnt be able to set it through JavaScript. The only way it works is if I declare all the style attributes in the Div tag itself first. Is this how it works?
