The realization and use of JS's StringBuffer class

1. There is a StringBuffer class in <strong>java, JS is not the following to achieve a simple JS StringBuffer class. </strong>

2. //Create a StringBuffer class with two methods: One is the Append method, the other is the ToString method
4. function StringBuffer () {
6. this.__strings__ = [];
8. };
10. StringBuffer.prototype.append = function (str) {
12. This.__strings__.push (str);
14. };
16. StringBuffer.prototype.toString = function () {
18. return This.__strings__.join (");
20. };

Use of StringBuffer:

1. The main use of this instance is to stitch strings

2. function Gncomcard (companymsg) {
4. var buffer = new StringBuffer (); Declaring an object
6. Buffer.append (' <li> '); Append string, same as
8. Buffer.append (' <div class= ' Com_photo "><a href=" # "title=" user picture ">
10. Buffer.append (Companymsg.userphoto);
12. Buffer.append (' ></img></a></div> ');
14. Buffer.append (' <div class= ' com_msg ' > ');
16. Buffer.append (' <div><a class= ' com_comname ' > ' + companymsg.companymastername+ ' </a> < Span class= "Com_time" > '
18. + formatdate (companymsg.crtime) + ' </span></div> ');
20. Buffer.append (' </div><div class= ' news > ');
22. if (companymsg.newsid! = null) {
24. Buffer.append (' <a href= ' ' +companymsg.newsid+' "title=" News "class=" com_newsname "> ' +  Companymsg.newstitle + ' </a> ');
26. } Else {
28. Buffer.append (' <a href= ' javascript:void (0) "class=" Com_newsname "> ' + companymsg.newstitle + ' </a  > ');
30. }
32. if (companymsg.newscontent! = null) {
34. Buffer.append (' <div class= ' com_sh ><span class= ' toggle ' >>> expand </span></div> ');
36. Buffer.append (' <div class= ' com_newscontent ' > ' + companymsg.newscontent + ' </div> ');
38. }
40. Buffer.append (' </div> ');
42. Buffer.append (' <div class= "comment" & Gt;<a href= "javascript:void (0)" style= "Float:left" title= "tracking Company"  >& lt;span class= "track" ></span></a><input type= "text" ></input></div> ");
44. Buffer.append (' </div></li> ');
46. return buffer.tostring (); //stitching into a string
48. }
