Jquery加载时从后台读取数据绑定到dropdownList实例

$(document).ready(function () { 
loadSchools(); 
}); 
function loadSchools() { 
var url = "@Url.Action("GetSchools")"; 
$.ajax({ 
url: url, 
type: "GET", 
dataType: "json", 
error: function () { 
alert("Error"); 
}, 
success: function (data) { 
var items = ""; 
$.each(data, function (i, school) { 
items += "<option value=\"" + school.SchoolId + "\">" + school.SchoolName + "</option>"; 
}); 
$("#SchoolId").html(items); 
} 
}); 
}
