jq $ .get () and $ .post () method for transmitting background data

$.get(URL,data(无数据时候传入{}),function(data(回调数据),status(可选),xhr(可选)),dataType(可选/默认为JSON));

Case:

    $.get('1.php',{},function(dataLength){
        dataLength = JSON.parse(dataLength).dataLength;
    });

\$.post(url,data,success(data, textStatus(可选), jqXHR(可选)),dataType(可选))
是简写版的\$.ajax()

Case:

  $.post("demo_ajax_gethint.asp",{suggest:txt},function(result){
    data=JSON.parse(result);
  });
