No-refreshing ajax comments and refreshing ajax comments

This is the message board interface. When you click to submit a message, it is automatically submitted to my message.

If the message content is blank or the gray content is left blank, enter the message content. When the user fills in the information, the number of words of the current message will be displayed in the lower right corner.

Below is the javascript code

// Remove the left and right corner brackets and use the string after removing the space to replace the function replaceBrackets (id) {var inputValue =$ ("#" + id ). val (); while (inputValue. indexOf ("<")! =-1) {inputValue = inputValue. replace ("<", "[");} while (inputValue. indexOf ("> ")! =-1) {inputValue = inputValue. replace (">", "]") ;}while (inputValue. indexOf ("&")! =-1) {inputValue = inputValue. replace ("&", "") ;}$ ("#" + id ). val (inputValue);} function replaceChar (name, char) {var inputValue = $ ("#" + name ). val (); while (inputValue. indexOf (char )! =-1) {inputValue = inputValue. replace (char, "") ;}return inputValue ;}$ ("# txtMessage "). blur (function () {$ ("# txtMessage "). val (replaceChar ("txtMessage", "<! -- "); If ($ (" # txtMessage "). val () = "") {document. getElementById ("txtMessage "). style. color = "# 8C8C8C"; $ ("# txtMessage "). val ("message content not filled"); return false;} replaceBrackets ("txtMessage"); return true ;}); $ ("# txtMessage "). focus (function () {if ($ ("# txtMessage "). val () = "no message filled") {document. getElementById ("txtMessage "). style. color = "#000000"; $ ("# txtMessage "). val ("") ;}}); function txtanum (id, Name) // count the input words of txta {var maxl = 151; var num = 150; var content = $ ("#" + id ). val (); content. slice (0, maxl); var nowlength = content. length; if (nowlength> = 0) {if (nowlength <num) $ ("#" + name ). text (nowlength); else $ ("#" + name ). text (num);} else $ ("#" + id ). val (content. substring (0, maxl-1); if (nowlength = 0) $ ("#" + name ). text (0); if (nowlength> num) $ ("#" + id ). val (content. substring (0, num);} var isSubmit = false; $ ('# submessage '). click (function () {if (isSubmit) {return;} isSubmit = true; if ($ ("# txtMessage "). val () = "no message filled" | $. trim ($ ("# txtMessage "). val () = "") {alert ("Enter the message content! "); IsSubmit = false; return;} $. ajax ({type: "POST", url: app_param.path_context + "/user/member/msgboard/save", data: {"context": ($ ("# txtMessage "). val ()}, error: function () {isSubmit = false;}, success: function (data) {if (data) {addRow (data); isSubmit = false; $ ('# zanwu '). hide (); document. getElementById ("txtMessage "). style. color = "# 8C8C8C"; $ ("# txtMessage "). val ("no message content filled") ;}}); function addRow (messageboard) {var table =$ ("# tblmsg"); var html = []; html. push ("<tr>"); html. push ("<td class ='m _ time'>"); html. push (messageboard. createDate); html. push ("</td>"); html. push ("<td>"); html. push (messageboard. context); html. push ("</td>"); html. push ("<td style = 'border-right: 0; 'class ='m _ order_procz'>"); html. push ("<a class = 'xxx' href = 'messagereply/" + messageboard. id + "'> View </a>"); html. push ("</td>"); html. push ("</tr>"); html = html. join (''); table. append (html );}});
