我正在执行更新操作，请在弹出窗口中按“编辑”按钮加载数据，当我更新任何字段然后更改事件不被调用时。更改事件用于在文本中显示说明。 在PurchaseCodeU网格中调用此函数以填充此文本框值 txtUPurCode ，然后在我更改某些内容但未更改事件时调用。 谁能告诉我我哪里错了，我的代码有什么问题。
jquery
<script>
// Purchase Code For Update
var purchaseCU = $("#txtUPurCode").val();
PurchaseCodeU(purchaseCU);
function PurchaseCodeU(purchaseCU) {
$.ajax({
url: "/Home/chartofAccount",
type: "GET",
contentType: "application/json;charset=UTF-8",
data: {
'glCode': purchaseCU
},
dataType: "json",
success: function (result) {
$('#UPurCodeDescription').val(result);
},
error: function (errormessage) {
alert(errormessage.responseText);
}
});
return false;
}
$('#txtUPurCode').change(function () {
var pC = $("#txtUPurCode").val();
function PUC(pC) {
$.ajax({
url: "/Home/chartofAccount",
type: "GET",
contentType: "application/json;charset=UTF-8",
data: {
'glCode': pC
},
dataType: "json",
success: function (result) {
$('#UPurCodeDescription').val(result);
},
error: function (errormessage) {
alert(errormessage.responseText);
}
});
return false;
}
})
</script>
