jquery 之ajax,get,post异步请求简单代码模版

$.get("../cart/cart_list.do",
    "productId=" + productId,
    function(data){
    alert(data);
});

 

$.post("../cart/cart_list.do",
    "productId=" + productId,
    function (data) {
    alert(data);
});

 

url = __ctx + "/maintenance/onceequipment/tdJxdEquipment/dialogGltxfsdSend.ht";

var params = {
    "ids": arrIds,
    "id": id
};
$.ajax({
    "url": url,
    "type": "post",
    "async": true,
    "data": params,
    "dataType": "json",
    "success": function (data) {
        if (data == 'true') {
