Encapsulate instance _ajax related to Ajax network requests

Instance code:

Encapsulated AJAX Network Request function//obj is an object function AJAX (obj) {//Cross-domain request if (Obj.datatype = "Jsonp") {//here callback must be It's a global variable. The variable cannot be destroyed//processed when the function name (prevents multiple network request functions from having the same name disorder) var hehe = "CallBack" + "_" + New Date (). Gettim
      E () + "_" + String (Math.random ()). Replace (".", "");
      Window[hehe] = obj.success;
      Create a script tag var sc = document.createelement ("script");
      SC.SRC = Obj.url + "?" + "cb=" + hehe;
      Console.log (SC.SRC);
      Document.body.appendChild (SC);
      Document.body.removeChild (SC);
    Return

  }else{ajaxobj = new ActiveXObject ("Microsoft.XMLHTTP"); //Set the type of request Obj.type = Obj.type.toUpperCase () | |

  "Get"; If it is a GET request and you need to pass the parameter, you need to give the URL a concatenation parameter if (Obj.type = = "Get") {var arr = [];//definition array is used to store the object in the data for the (Var key in OB
    J.data) {Arr.push (key + "=" + Obj.data[key]); ///With & spacer array Let it be transformed into something like this: the name=lxl&age=18 form var str = arr.join ("&"); Obj.url = Obj.url + "?"

    Dial-up Ajaxobj.open (obj.type,obj.url,true);

Above the AJAX network request for the package example is a small series to share all the content, hope to give you a reference, but also hope that we support the cloud habitat community.
