Question

This is in an HTML file. In the else section, I want to call a show-form(); function which is in an example.php page. Also, what’s the complete syntax for $.post();?

<script type="text/javascript">
    function nis(id){
        $(id).show("slow").delay(4000).hide("slow");
    }

    $(function() {
        setAutoComplete("searchField", "results", "autocomplete.php?part=");

        $('form[name=frm]').submit(function(event) {
            if($("#searchField").val().length===0)
            {
                nis('.divmsg');
                return false;
            }
            else {
                $.post("example.php", function() {});
            }
        });
    });
</script>

This is in example.php .. which is for giving you a declaration for any word you write in searchField.

<?php
    function show_form()
    {
        echo'<div  class="divmsg"> Wronge input :: </div>';
        echo'  <form name="frm" method="post" action="index.php?act=sm"> ';
        echo'<p class="textplz">Tybe a Definition you want ?!';
        echo'<p id="auto" >';
        echo'Word : <input id="searchField" type="text" name="searchField" />    <input  id="for-submitbutton" type="submit" name="sbm" value="Definition" /> ';
        echo' </p> </p>  </form>';
    }

    function submited()
    {
        require("dbconn.inc");
        $word=$_POST['searchField'];
        $sql="select * from definition where word like '".$word."'";

        $result=mysql_query($sql,$con);
        if(@mysql_num_rows($result)!=0)
        {
            while($rows=mysql_fetch_array($result))
            {
             $vie=$rows["declation"];
            }
            echo('
                <br />
                <br />
                <form name="frm" method="post" action="index.php?act=sm"> <p id="auto" >
                    Word : <input id="searchField" type="text" name="searchField" /> <input id="for-submitbutton" type="submit" name="sbm" value="Definition" />
                </p> </form> ');
            echo('<div class="answer">');
            print $word ;
            echo('<br><p id="dev">');
            print $vie;
            echo ("</h4><br></p></div>");
        }
    }
 ?>

Answer 1

1. The complete syntax for $.post() is:

   $.post(url, data, callback, type);
   

2. In your case:

   $.post("example.php", null,  function() {});
   

If you want to send some parameters, use {param1: "123", param2: "123} instead of null.
