Ajax未捕获TypeError:无法重新定义属性：
Ajax未捕获TypeError:无法重新定义属性：
提问于 2018-06-09 02:26:19
请帮助我摆脱这个问题，当我运行以下ajax请求代码来填充选择框时，取决于用户对第一个选择框的选择：
$("#item_type").change(function () {
var item_type = $("#item_type").val();
if(item_type == "spare_parts")
{
$.ajax({
type: "GET",
url: "http://example.com/index.php/inventory/spend_receive_receipt/get_items/",
dataType: 'json',
success: function (data) {
var Areas = data.length;
elements = "<option value='0'>إختر الصنف</option>";
for (var i = 0; i < Areas; i++) {
elements += "<option value='" + data[i]['id'] + "'>" + data[i]['item_name'] + "</option>";
};
elements_label = "الأصناف";
$("#items_devices").html(elements);
// $("#items_devices_label").html(elements_label);
};
error: function (req, err) {
console.log("my message : " + err);
};
});
}else if (item_type == "devices")
{
$.ajax({
type: "GET",
url: "http://example.com/index.php/inventory/spend_receive_receipt/get_devices/"
dataType: "json",
success: function (data) {
var Areas = data.length;
elements = "<option value='0'>إختر الجهاز</option>";
for (var i = 0; i < Areas; i++) {
elements += "<option value='" + data[i]['id'] + "'>" + data[i]["device_name"] + "</option>";
}
elements_label = "الأجهزة";
$("#items_devices").html(elements);
// $("#items_devices_label").html(elements_label);
}
error: function (req, err) {
console.log("my message : " + err);
};
});
}
});我在控制台中得到了以下错误，请求没有成功
Uncaught TypeError: Cannot redefine property: BetterJsPop

at inject (<anonymous>:20:10)
at <anonymous>:510:11
at <anonymous>:511:11还有这个

这对我很有效，但我不知道问题出在哪里
function get_items_devices(item_type) {
if(item_type == 'spare_parts')
{
item_type = 'spare_parts';
}else if(item_type == 'devices'){
item_type = 'devices';
}
if (item_type == 'spare_parts'){
$.ajax({
type : "GET",
url : 'http://example.com/index.php/inventory/spend_receive_receipt/get_items/',
dataType : 'json',
success: function(data) {
var Areas = data.length;
elements = "<option value='0' disabled selected>إختر الصنف</option>";
for (var i = 0; i < Areas; i++) {
elements += "<option value='" + data[i]['id'] + "'>" + data[i]['item_name'] + "</option>";
}
$("#items_devices").html(elements);
var elements_label = "الأصناف";
$("#items_devices_label").html(elements_label);
},
error: function(req, err){ console.log('my message : ' + err); }
});
}else if (item_type == 'devices'){
$.ajax({
type : "GET",
url : 'http://example.com/index.php/inventory/spend_receive_receipt/get_devices/',
dataType : 'json',
success: function(data) {
var Areas = data.length;
elements = "<option value='0' disabled selected>إختر الجهاز</option>";
for (var i = 0; i < Areas; i++) {
elements += "<option value='" + data[i]['id'] + "'>" + data[i]['device_name'] + "</option>";
}
$("#items_devices").html(elements);
var elements_label = "الأجهزة";
$("#items_devices_label").html(elements_label);
},
error: function(req, err){ console.log('my message : ' + err); }
});
}
