选择器是一个简单的、容易使用、多功能和可定制的Javascript颜色选择器。
使用选择器非常简单:
var parent = document.getElementById('parent');
var picker = new Picker(parent);
parent.onclick = function() {
picker.show();
};
picker.on_done = function(colour) {
parent.style.background = colour.rgba().toString();
};
<script src="picker.min.js"></script>
<div id="parent">click me</div>
<script>
/* STEP 1 */
/* Create a new picker object and set the parent element. */
var parent = document.getElementById('parent'); /* or jQuery */ $('#parent');
var picker = new Picker(parent);
/* STEP 2 */
/* Set Picker to open when you want, when the parent is clicked for example. */
parent.onclick = function() {
picker.show();
};
/* STEP 3 */
/*
You can do what you want with the chosen colour using two events,
on_change and on_done.
*/
picker.on_done = function(colour) {
/*
You can get the colour using the hsl(), hsla(), rgb(), rgba() and hex() functions.
Each function returns an object containing each component (e.g r, g and b) and a
toString() function, which returns the colour as a string to use with CSS or JS.
E.g 'rgba(255, 0, 0, 0.4)'.
*/
parent.style.background = colour.rgba().toString();
};
/* on_change is called every time the selection is changed without clicking 'ok' */
</script>
也有许多选项,你可以选择。
var picker = new Picker({
/* The colour picker's parent */
parent: (parent element),
/*
Where the colour picker is relative to the parent.
Defaults to 'right'.
*/
orientation: ('left', 'right', 'top', 'bottom', 'centre', 'center'),
/*
The colour picker's x position relative to the parent.
Defaults to 'auto'.
*/
x: (number),
/*
The colour picker's y position relative to the parent.
Defaults to 'auto'.
*/
y: (number),
/*
The colour picker's arrow size.
Defaults to 20.
*/
arrow_size: (number)
});
你可以定制CSS源文件,或做如下:
picker.wrapper.background = '#333';
简单!
