在jQuery多选下拉列表中设置值 [英] Set values in jquery multiselect dropdown

问题描述

我想根据从数据库中获取的该项的VALUE，在jQuery multiselect dropdown中设置jQuery multiselect dropdown的多个ITEMS，以","分隔.

I want to set the multiple ITEMS in jQuery multiselect dropdown depending on the VALUE of that item, which I'm getting from database, separated by ",".

我正在将获取的数据保存在hidden field中.

I'm saving this fetched data in hidden field.

例如

隐藏字段:hdnLots = 64,65 ，商品编号:64 = Lot 1, 65 = Lot2

Hidden field: hdnLots = 64,65 , Items for lot No.: 64 = Lot 1, 65 = Lot2

因此，当我得到hdnLot=65时，则在jQuery Multiselect dropdown中仅需要选择Lot2. 同样是64,65.即当多个值比所有选择需要的那些值入围.

So when I get the hdnLot=65, then in jQuery Multiselect dropdown only Lot2 needed to be selected. And same for 64,65. i.e. When multiple values are selected than all those values needed to seleted.

我已经尝试过: Jquery multiselect -设置在多选下拉列表中选择的值

我为此编写的代码是:

if ($("#<%= btnUpdateProject.ClientId %>").css('display') == "inline-block") 
{
   debugger;
   var dataarray = document.getElementById('<%= hdnLots.ClientId %>').value.split(",");
   $("#<%= ddlNoOfLots.clientid %>").val(dataarray);
}

$("select").multiselect({
   selectedText: "# of # selected"
});
var hidValue = $("#hidSelectedOptions").val();
alert(hidValue);
var selectedOptions = hidValue.split(",");
for(var i in selectedOptions) {
    var optionVal = selectedOptions[i];
    $("select").find("option[value="+optionVal+"]").prop("selected", "selected");
}
$("select").multiselect('reload');
});
