asp.net 向javascript传递参数的问题
这是javascript函数
function changeASort(DDLA,DDLC) {
var id = DDLA;
var id2 = DDLC;
alert(id);
alert(id2);
}
这是asp.net的部分函数
DropDownList DDListSort = new DropDownList();
DDListSort.ID = "DDListSort" + ControlName;
string DDListASortID = "DDListASort" + ControlName;
DDListSort.Attributes.Add("onchange", "changeASort(" + DDListSort.ID + "," + DDListASortID + ");");
问题:
触发changeASort函数,可是DDLA的值不是等于DDListSort.ID ,而是等于object
------解决方案--------------------加个单引号
DDListSort.Attributes.Add("onchange", "changeASort('" + DDListSort.ID + "'," + DDListASortID + ");");
------解决方案--------------------加个单引号
DDListSort.Attributes.Add("onchange", "changeASort( '" + DDListSort.ID + " '," + DDListASortID + ");");
正解!
------解决方案--------------------DDListSort.Attributes.Add("onchange", "changeASort( '" + DDListSort.ID + " '," + DDListASortID + ");");
传值应该加上单引号。JS中值不为空时就表示为一个对象object,你可以现typeof测试一下。。。
