2、修改ySelect.js

3、呼叫
var set_ySelect;
$(function () {
var $that = $;
set_ySelect= function (classname,changeBack,isCheck) {
$that("." + classname).ySelect({
numDisplayed: 10,
changeBack: changeBack,
isCheck,isCheck
});
}
})
//員工角色ajax
scope.GetRoleInfoAll = function () {
Ajax.post("/SysBase/Staff/RoleInfoAll", null, function (result) {
scope.RoleInfoAll = [];
if (result.Data != null && result.Data.length > 0) {
var options = "";
var rolds = scope.StaffInfo.RoleId.split(',');//之前儲存的角色id
//在獲取資料後才執行ySelect,並且不能用ng-repeat繫結下拉框資料
angular.forEach(result.Data, function (v) {
scope.RoleInfoAll.push(v);
//設定selected後自動選中
options += "<option value='" + v.RoleId + "' "+(rolds.indexOf(v.RoleId+"")>-1?'selected="true"':'')+">" + v.RoleName + "</option>";
});
$(".RoleInfoAll").append(options);
set_ySelect("RoleInfoAll", function (texts, values) {
scope.StaffInfo.RoleId = "";
scope.StaffInfo.RoleName = texts;//返回的texts名字是逗號隔開
//返回的id值是陣列values
if (values.length > 0) {
for (var i = 0; i < values.length; i++) {
scope.StaffInfo.RoleId += values[i] + ",";
}
if (scope.StaffInfo.RoleId[scope.StaffInfo.RoleId.length - 1] == ',') {
scope.StaffInfo.RoleId=scope.StaffInfo.RoleId.substr(0,scope.StaffInfo.RoleId.length-1) ;
}
}
});
}
});
