如何使用javascript的onchange for @ Html.DropDownListFor

Question

如何为@ Html.DropDownListFor使用onchange事件

@Html.DropDownListFor(model => Tlitem.JobType, (SelectList)newSelectList, new { @class = "form-control js-select js-noFilter hidden", size = "2", @value = 0, Id = "JobType" + t ,@onchange="alert('hello');"});

上面的代码不起作用

Answer 1

在onclick上，只需将其更改为onChange="javascript://whatever function you want()"

例如

@Html.DropDownListFor(model => Tlitem.JobType, (SelectList)newSelectList, new { @class = "form-control js-select js-noFilter hidden", size = "2", @value = 0, Id = "JobType" + t ,@onchange="javascript:onChangeFunction()";

Answer 2

您可以使用：

document.getElementById("JobType").addEventListener("change", myFunction);

function myFunction() {

}

或者如果您使用的是JQuery：

$("#JobType").change(function() {
});
