Javascript 尝试使用JQUERY用JSON数据填充Select
从ajax调用中检索数据似乎一切都很顺利,但我无法用JSON内容填充select,它会在控制台中不断触发此错误:Javascript 尝试使用JQUERY用JSON数据填充Select,javascript,jquery,json,ajax,Javascript,Jquery,Json,Ajax,从ajax调用中检索数据似乎一切都很顺利,但我无法用JSON内容填充select,它会在控制台中不断触发此错误: Uncaught TypeError: Cannot use 'in' operator to search for 'length' in [{"0":"1","s_id":"1","1":"RTG","s_name":"RTG"},{"0":"2","s_id":"2","1":"IR","s_name":"IR"},{"0":"3","s_id":"3","1":"NCR","

JS就是这个
function populateSelect(et_id){
$.ajax({
url: "http://localhost/new_dec/modules/Utils/searchAvailableStatus.php",
type: "get", //send it through get method
data:{et_id:et_id},
success: function(response) {
var $select = $('#newStatus');
$.each(response,function(key, value)
{
$select.append('<option value=' + key + '>' + value + '</option>');
});
},
error: function(xhr) {
//Do Something to handle error
}
});
}
假设服务器端脚本没有设置正确的内容类型:application/json响应头,则需要将响应解析为json 然后,您可以使用$.each函数循环数据:
var json = $.parseJSON(response);

我想你需要这样的东西
function populateSelect(et_id){
$.ajax({
url: "http://localhost/new_dec/modules/Utils/searchAvailableStatus.php",
type: "get", //send it through get method
data:{et_id:et_id},
success: function(response) {
var json = $.parseJSON(response);
var $select = $('#newStatus');
$.each(json ,function(index, object)
{
$select.append('<option value=' + object.s_id+ '>' + object.s_name+ '</option>');
});
},
error: function(xhr) {
//Do Something to handle error
}
});
}

发布更多信息。您的JSON看起来像什么?更好的是,创建一个JSFIDLE。发布更多信息。您的JSON看起来像什么?更好的方法是创建一个JSFIDLE。好的,现在添加选项的过程很好,但加载方式如下:[object object][object object][object object][object object][object object][object object][object object]好的,现在添加选项的过程很好,但加载方式如下:[object object][object object object object][object object object object object object]
