How do I format a string in different colors with canvas:fillText(...); I want the following result: str = "This is blue", where "This is" is black color and "blue" is blue color.

I have a Number as a String. It goes from 1 to 999 but I need to set the format so that it has leading Zeros. So 1 is 001 and 2 is 002 and 99 is 099.
Is there a way to do this in JavaScript?
Thanks,

How to do that in JS?
I want to delete some lines on the canvas that i have created in HTML5 (with the <canvas> tag). I know one solution and that is using clearRect() (give this function the HEIGHT and WIDTH of the canvas and you clears the whole canvas.).But i don't want to clear the whole canvas, i only want to delete a few lines made by the function lineTo().
View 1 Replies View RelatedI have a menu in which is applied typeface script. Typeface 0.11 version doesn't support hover on links. There is an experimental version but doesn't work very well for me, so i tried to implement hover by myself.
Problem is: hover works pretty well changing canvas context property fillColor and then calling fill(), but the stroke on hovered voice remains on another color. Difficult to explain, so i put some test code online: TEST CODE As you can see, passing with mouse on the menu voices triggers the hover and the element change, but remains bordered in red.

I am working on a Windows application (in C#) that displays some HTML. In one place the HTML is a status window. What happens is the static HTML page is embedded into the application. The static page displayed and then the C# code gets a hold of the HTML DOM from the web browser and updates what pieces need to be updated.
What I need to do now is change the colors of everything on the static page. At present there is an embedded CSS style in the HTML and all the colors are defined there. Using the DOM, via C# code, how do I change the colors of everything?
1: Can I simply update the CSS and it will auto magically happen? If so, how does one update the CSS via the DOM?
2: Do I need to go to each individual item and change the color there?
3: Is there a better way to do this all the way around?
I am displaying an image from database using php .... the problem is that i want to give a row of colors beneath the image .... so that when a user clicks on one of the color .... the image should change accordingly ... in my case i am displaying a shopping bag and i want to give a row beaneath as available colors ..... so that when a user clicks on a color the image should change without refreshing. I ve no idea what is this functionality or whether it is already there in the open.
View 4 Replies View RelatedI just read "JavaScript 101 - Part 1," and had a question about the specific part linked to above:
Is there a more efficient way of switching colors every row other than calling it every time you want to start a new row? Also, how can the row number be increased each time if the variable rownumber is only increased by one within the second half of the function? What if the row is even? Is the number not increased?

I want to run a script that will cycle through all the available colors, but can't even get the following to work:
<html>
<head>
<script type="text/javascript">
function setStyle()
{
i=255;
[Code]....
What am I doing wrong? Eventually I want put all the above in a loop that updates 1,j, and k - and so cycles through all colors.
I got 3 sections on the site, at the bottom of each are 5 bars which are used to change the text color. I'm trying to minimize the code, so I created an array which contains all the colors, but I'm not sure where to put the call to the array. If I put it in the for loop, the selected color will always be green no matter which color you click. The bars should also go up to 40px when clicked and when the next bar is clicked the current bar at 40px should go back to it's originals size(20px)
this is the JS
var colors = new Array(4);
colors[0] = "#ed1c24";
colors[1] = "#736257";
colors[2] = "#620460";
colors[3] = "#e87e01";
colors[4] = "#00a650";

I have a form which displays correctly in FireFox. In IE, 2 of the 3 fields appear with a pale yellow (#FCFEA4) background color. Why is this, and how can I fix it?
There is only 1 style sheet, and everything else conforms to the sheet. Remember: this problem is in IE, not FireFox. My task is to make it render correctly in IE.
<FORM ACTION="/bbp/t11s.php" METHOD="GET" name="lastform">
<div style="padding-left:10px;font-family:monospace;">
First Name <input type=text value="" name="fname">
</div>
<div style="padding-left:10px;font-family:monospace;">
Last Name <input type=text value="" name="lname">
</div>
<div style="padding-left:10px;font-family:monospace;">
Building <input type=text value="" name="bld">

<br>
<div style="padding-left:75px;"><input type="Submit" value=" Post Information " /></div>
</form> Code:
Out of pure curiosity: Assuming tabulated data in HTML is being generated by a PHP script, would it be better to alternate each row's background color with PHP or rely on JS to do it? One is run client-side and the other server-side so my guess you have to take the whole web app as a whole and see which side should be spared the additional workload. Is it situational or is there an absolute rule? In a vacuum, I guess you could argue PHP would be better since it cannot be turned off in the way JS can (unless plugins like NoScript can block PHP as well), but I don't have enough experience with either to be sure.

View 2 Replies View RelatedI'm writing a FireFox extension and I have the dom and therefor the
links[] collection
window.getBrowser().contentDocument.links[i]

For example. If I have this loop
var number_of_links = window.getBrowser().contentDocument.links.length;
for (var i=0; i < number_of_links; i++)

var domain = window.getBrowser().contentDocument.links[i].hostname;

I have the followingcode linesin myJavaScriptcode:var colors = ["#F08", "#0B8", "#04F", "#FD0", "#808", "#F20"];This sets the bg colors of my divs. This var is only used here:

I need to make the backgrounds on certain rows a different color to get the info to read better. I used the following:
<!-- Directory of Staff Row Backgrounds -->
<script type="text/javascript">
$(document).ready(function() {
$('tr:odd').addClass('odd');
});
</script>
But instead of starting over with a new table it seems to just have counted them all so it looks off. Here is the page: [URL].
I seem to be having a slight problem.
Code:
<script type="text/javascript">
<!--
document.bgColor='#33CCFF';
var x = 300;
while (x < 1500)
[Code]...
Basically, this makes the background flicker for a brief second. Great. However, if I set a background color using CSS (so the page isn't white if javascript is turned off) the flicker won't work.
My Form Name Attribute is changing the background color of the field. When I take the name attribute out of the form element, it looks ok. Wondering if maybe it has something to do with the onfocus and onblur that I have in each element.

I'm new to Javascript so bear with me. I'm trying to change the bgcolor of specific rows in a table, here's the code for one of the row:
<tr id="testing" valign="top" bgcolor="#<?= $defaultcolor;?>">
<td><?=$lang[store_name]?></td>
<td>
<select name="namebg" onChange="document.getElementbyId('testing').bgColor=this.options[this.selectedIndex].value">
<option selected="selected" value="">Select Row Color</option>
<option value="FFFFFF">White</option>
<option value="F0F8FF">AliceBlue</option>
<option value="00CC99">Green</option>
</select>
</td>
</tr>
I tried to use style.getBackgroundColor but that didn't work either, please, any help would be appreciated.

I am trying to write a very simple asteroids game for a presentation on
Ajax in July, to show that javascript can do more than it was able to a
couple of years ago.
I am working with the new canvas element. I have simplified my request.
Can I add a class to the canvas JS? Currently the fill colour is set with 'context.fillStyle="red";' I would love have this in a class as I want to change the colour of the fill with jQuery.
