用法

首先需要引入 jquery 1.4、jQuery UI theme, 和 jquery.multiselect. css . 我們?cè)谶@用的不是jQuery UI library本身,而是他的主題文件. 最簡(jiǎn)單的綁定select box方法:

?

    <select id="MySelectBox" multiple="multiple" name="MySelectBox"> <option value="1">Option 1</option> <option value="2">Option 2</option></select>

  

?

    $(document).ready(function(){
    $("#MySelectBox").multiSelect();
});
  

?

?

回調(diào)函數(shù)

?

比如其中的 onOpen 回調(diào)函數(shù), 如:

?

    $("#MySelectBox").multiSelect({
	onOpen: function(){
		var $checkboxes = $(this).find('input');
	}
});
  

?

onClick 回調(diào)函數(shù). Example:

?

    $("#MySelectBox").multiSelect({
	onClick: function(){
		if(this.checked){
			alert("I was just checked!");
		}
	}
});
  

?

更多回調(diào)函數(shù)請(qǐng)看下面列表.

?

重載項(xiàng)

參數(shù)選項(xiàng)均在 $.fn.multiSelect.defaults中保存 , 你可以如下改變默認(rèn)選項(xiàng):

?

     // set the minWidth parameter for all instances to 500 pixels
$.fn.multiSelect.defaults.minWidth = 500;
  

?

?

Passing a function to the selectedText parameter

As of 0.5, the selectedText parameter can accept an anonymous function with three arguments: the number of checkboxes checked, the total number of checkboxes, and an array of the checked checkbox DOM elements. As you can see in the example, this gives you 100% control of the display:

?

    $("#MySelectBox").multiSelect({
	selectedText: function(numChecked, numTotal, checkedInputs){

		// example: emulating the default behavior
		return numChecked + " checked"; 

		// example: emulating the selectedList option
		return (numChecked < = 5)
			? checkedInputs.map(function(element){ return element.title; }).join(', ')
			: numChecked + " checked";
	}
});
