我正在创建级联下拉列表,但出现错误:
function GetCity(_warehousesId) {
var procemessage = "<option value='0'> Please wait...</option>";
$("#ddlcity").html(procemessage).show();
var url = "/Carriage/GetCityByStaeId";
$.ajax({
url: url,
data: { warehousesid: _warehousesId },
cache: false,
type: "POST",
success: function (data) {
var markup = "<option value='0'>Select City</option>";
for (var x = 0; x < data.length; x++) {
markup += "<option value=" + data[x].Value + ">" + data[x].Text + "</option>";
}
$("#ddlcity").html(markup).show();
},
error: function (reponse) {
alert("error : " + reponse);
}
});
};
@using (Html.BeginForm())
{
@Html.DropDownListFor(m => m.StateModel, new SelectList(Model.StateModel, "WarehousesID", "Name"), new { @id = "ddlstate", @style = "width:200px;", @onchange = "javascript:GetCity(this.value);" })
<br />
<br />
<select id="ddlcity" name="ddlcity" style="width: 200px"></select>
<br /><br />
}
而且,我总是得到一个错误:“未定义GetCity”。我究竟做错了什么?
最佳答案
您的(function GetCity(_warehousesId) {})(jQuery)
是错误的。您尝试创建自执行功能,然后再尝试使用它。
它应该只是function GetCity(_warhouseId) {}
以便以后能够执行。
如果<script>
具有src
属性,则其中的任何内容都将被忽略。为jQuery和您的代码使用不同的标签:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script type="text/javascript">
function GetCity(_warehousesId) {}
</script>
关于javascript - jQuery GetCity未定义,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/43340215/
