A brief analysis of the problem of data binding in Bootstrip's select control_jquery

this problem took me a whole afternoon to figure out, and i finally solved it. the editor will share my credit below as a backup, and i hope it can help everyone.

the specific details are as follows:

$(function(){ 
var stu_no = freeUrl();
var data, subname="",data2;
var sbList = new Array();
$.ajax({ 
async: false ,
dataType: "json",
contentType: "application/json",
type: "post",
url: "../../control/student/stuMain.asmx/findAllSubject",
data:"{"+"'stu_no':'"+stu_no+"'}",
success: function (response) {
data2 = eval(response.d);
$.each(data2, function (i) {
$("<option value='" + i + "'>" + data2[i].科目名称 + "</option>").appendTo(".selectpicker");
});
$('.selectpicker').selectpicker({
//我是对所有的selectpicker操作一次性赋值，如果你想单独赋值，好ok，那么就这样赋值：
//appendTo("#editcolor .selectpicker"),就这样，在你select元素上面罩上一个div，
//用div的id就可以标记你要操作的selectpicker，也就是你想操作的select元素标签了
style: 'btn-info',
size: 8
})
}
})

the above is the editor's introduction to the issue of data binding in bootstrip's select control. i hope it will be helpful to you!
