Free Advanced DHTML Color Picker

〜によって COLOURlover インディアナ Fun, News, Popular, Products, Software, Tools

When we were developing COPASO, we found that we needed to have a more advanced color picker to work inside the application... and since COPASO is built with DHTML it was easy enough to pull out the picker to use on the other creation pages of our site. Once we'd modularized the color picker code it made sense to offer it to others to use on their own sites and projects. So here is the code to get our Color Picker working on your site for free. (We'll even host the files)

COLOURlovers Color Picker Demo

Here is the Code You Need & Examples...

Put this Code into Your HTML <head> Section:
<link rel="stylesheet" href="http://colourlovers.com.s3.amazonaws.com/COLOURloversColorPicker/COLOURloversColorPicker.css" type="text/css" media="all" />
<script type="text/JavaScript" src="http://colourlovers.com.s3.amazonaws.com/COLOURloversColorPicker/js/COLOURloversColorPicker.js"></script>

Put this Code into Your HTML <body> Section:
<div id="CLCP" class="CLCP"></div>
<script type="text/JavaScript">
  _whichField = "hexValue_0";
  CLCPHandler = function(_hex) {
    // This function gets called by the picker when the sliders are being dragged. The variable _hex contains the current hex value from the picker
    // This code serves as an example only, here we use it to do three things:
    // Here we simply drop the variable _hex into the input field, so we can see what the hex value coming from the picker is:
        document.getElementById(_whichField).value = _hex;
    // Here is where we color the BG of a div to preview the color:
document.getElementById("CLCPUpdateDiv").style.background = ("#" + _hex);
    // Giving you control over this function really puts the reigns in your hands. Rewrite this function as you see fit to really take control of this color picker.
  }
  // Settings:
  _CLCPdisplay = "none"; // Values: "none", "block". Default "none"
  _CLCPisDraggable = true; // Values: true, false. Default true
  _CLCPposition = "absolute"; // Values: "absolute", "relative". Default "absolute"
  _CLCPinitHex = "0039B3"; // Values: Any valid hex value. Default "ffffff"
  CLCPinitPicker();
</script>

Picker Attached to a Single Text Field:

Show picker and load the color to the left

Single Text Field Example Code

<input name="YourInputName" id="hexValue_0" style="width: 100px;" maxlength="6" value="0000FF" />
<a href="JavaScript:_whichField='hexValue_0';CLCPshowPicker({_hex: document.getElementById('hexValue_0').value});">Show picker and load the color to the left</a>

Picker Attached to Multiple Text Fields:

Show picker at x=300, y=1400 and don't update it's color

Show picker at x=12, y=1400 and load the color to the left

Show picker and load the color to the left

Show picker at mouse click and don't update it's color

Multiple Text Field Example Code:

<input name="YourInputName" id="multipleHexValue_0" style="width: 100px;" maxlength="6" value="FFFFFF" />
<a href="JavaScript:_whichField='multipleHexValue_0';CLCPshowPicker({_x: 300,_y: 200});">Show picker at x=300, y=200 and don't update it's color</a>
<input name="YourInputName" id="multipleHexValue_1" style="width: 100px;" maxlength="6" value="18AB49" />
<a href="JavaScript:_whichField='multipleHexValue_1';CLCPshowPicker({_hex: document.getElementById('multipleHexValue_1').value,_x: 12,_y: 400});">Show picker at x=12, y=400 and load the color to the left</a>
<input name="YourInputName" id="multipleHexValue_2" style="width: 100px;" maxlength="6" value="FF0000" />
<a href="JavaScript:_whichField='multipleHexValue_2';CLCPshowPicker({_hex: document.getElementById('multipleHexValue_2').value});">Show picker and load the color to the left</a>
<input name="YourInputName" id="multipleHexValue_3" style="width: 100px;" maxlength="6" value="FFFFFF" />
<a href="JavaScript:_whichField='multipleHexValue_3';CLCPshowPicker();">Show picker at mouse click and don't update it's color</a>
<input name="YourInputName" id="multipleHexValue_4" style="width: 100px;" maxlength="6" value="000000" />
<img src="http://colourlovers.com.s3.amazonaws.com/images/v3/color_wheel.png" style="vertical-align: -20%; cursor: pointer;" onclick="_whichField = 'multipleHexValue_4'; CLCPshowPicker();" alt="Show picker at mouse click and don't update it's color" title="Show picker at mouse click and don't update it's color" /> [Example with an image]

Here is a break down of the object passed to CLCPshowPicker()

{
  _hex: "FF4400", // When a valid hex value is passed, it will set the picker to this hex. Otherwise the picker will not change it's current color [if any].
  _x: 12, // If a x coordinate is passed, the picker will move to the x value. Otherwise, the x coordinate from the mouse click will be used.
  _y: 400 // If a y coordinate is passed, the picker will move to the y value. Otherwise, the y coordinate from the mouse click will be used.
  // All of these variables are optional
}
