javascript - Add content to div with php dynamically -


so i'm making contact form. when form submitted want add success or error message bootstrap modal.

here button submits form , opens modal.

<input class="btn btn-info" type="submit" value="submit" name="submit" data-toggle="modal" href="#contactmodal"/>

so when button clicked submits form , opens modal. there way add string of text modal dynamically upon success or failure of script?

here php success/failure action currently

if ($success){ print "<meta http-equiv="refresh" content="0;url=contactthanks.html">"; } else{   print "<meta http-equiv="refresh" content="0;url=error.html">"; }

but want add content modal instead of adding <meta> tag redirects page

here modal code 

<div id="contactmodal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="mymodallabel" aria-hidden="true">   <div class="modal-header">     <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>     <h3 id="mymodallabel">thanks!</h3>   </div>   <div class="modal-body">     <p>i'm pretty busy i'll try best message <strong>asap</strong>!</p>   </div>   <div class="modal-footer">     <button class="btn btn-primary" data-dismiss="modal" aria-hidden="true">close</button>   </div> </div>

so how print inside of <div> within modal without refreshing page or redirecting?

i don't know php or ajax , i'm not starting begin js , jquery (two days exact)

you cannot submit form , not have page refresh. want use ajax request php instead, return success/failure status json, use conditionally add content div javascript.

instead of form, use normal <input type="button" /> onclick="somefunction" somefunction makes ajax call.

you want use jquery.

your php 

//do submitted values  if ($success){     echo json_encode(true); } else{     echo json_encode(false); }

and ajax call like

$.ajax({     type: "post",     url: "dosomething.php",     data: { formvalue1 = <get value using jquery>, etc... }     datatype: "json",     success: processdata,     error: function(){ alert("failed"); } });  function processdata(data) {     if(data) {         $("div#divid").html("what want add inside div");     } }
