[英]Uncaught Type: Undefined is not a function JS error
I have been looking for this and tried with lot of found solutions but that didn't work in my case. 我一直在寻找并尝试使用许多找到的解决方案,但在我的情况下不起作用。 In my MVC 4 application with dropdown change event I am calling a JS method to pass the selected value to the controller which works fine but in console I've been getting this error continuoulsy in every change event.
在我的带有下拉更改事件的MVC 4应用程序中,我正在调用JS方法,以将选定的值传递给控制器,该控制器可以正常工作,但是在控制台中,每次更改事件中我都会不断收到此错误。
Following is my razor source for dropdown: 以下是我的下拉列表的剃须刀来源:
<div>
@Html.LabelFor(model => model.CustId)
@Html.DropDownListFor(model => model.CustId, new SelectList(Model.ddlCust, "Value", "Text"), "All Customer", new { id = "CustID", onchange = "ShowCust()", @class = "form-control" })
@Html.ValidationMessageFor(model => model.CustId)
</div>
And my JS client function looks like: 我的JS客户端函数如下所示:
<script>
function ShowCust() {
var custId = $("#CustID").val();
var Url = "@Url.Content("~/Customer/GetCustId")";
$.ajax({
url: Url,
type: 'POST',
dataType: 'json',
data: { CustID: custId },
success: function (data) {
return data;
}
});
}
</script>
In Console it throws the error on every dropdown change: 在控制台中,它会在每次下拉更改时引发错误:
uncaught type error: undefined is not a function.
And finally in source it shows as: 最后在源代码中显示为:
<script>(function() {with (this[2]) {with (this[1]) {with (this[0]) {return function(event) {ShowCust()
};}}}})</script>
Also it marks the part with underline in braces before function ShowCust ( {
ShowCust). 另外,它还在函数ShowCust(
{
ShowCust)之前的括号中用下划线标记该部分。
I am not able to figure out what exactly I am doing mistake over here. 我无法弄清楚我在这里到底在做什么错。
Does anyone see any issues with my html or javascript? 有人看到我的html或javascript有任何问题吗? Or the way I written the script?
还是我编写脚本的方式? Thanks in advance.
提前致谢。
I think you have miss out the '@' for Id & onChange
new { @id = "CustID", @onchange = "ShowCust()", @class = "form-control" }) new {@id =“ CustID”,@onchange =“ ShowCust()”,@class =“ form-control”})
@id = "CustID" @onchange = "ShowCust()" @id =“ CustID” @onchange =“ ShowCust()”
