复制代码 代码如下:

// Update the textbox with the total number of selected items, and determine select all

$("#id").updateSelected()

// Update the dropdown options

$("#id").multiSelectOptionsUpdate()

// Hide the dropdown

$("#id").multiSelectOptionsHide()

// Show the dropdown

$("#id").multiSelectOptionsShow()

// get a coma-delimited list of selected values

$("#id").selectedValuesString

使用javascript 设置多选框的默认选中项。

复制代码 代码如下:

$("#id").attr("value","");//清空选中项。

var ids='1,3,6';//设置选中框ID。

var id_Ojbect=(ids).split(",");//分割为Ojbect数组。

var count=$("#id option").length;//获取下拉框的长度。

for(var c=0;c<id_Ojbect.length;c++){

for(var c_i=0;c_i<count;c_i++)

{

if($("#id").get(0).options[c_i].text == id_Ojbect[c])

{

$("#id").get(0).options[c_i].selected = true;//设置为选中。

}

}

}
