Javascript working only on page refresh in jQuery mobile

问题

I am currently working with jquery mobile with JSP along with Struts. The problem is the javascript function gets called only after the page is refreshed once. The script is placed within the data-role 'page'. But the problem still persists. Currently am using jQuery 1.0 stable version. Here is my code ..

<body>
    <div data-role="page" id="webtosms">

        <script language="javascript">

        function phonenumlen(){         //Mobile no validation
            var numlen = mobileno.value.length;
            //alert(numlen);
            if(numlen==0){
                alert('Mobile Number cannot be left blank');
                return false;
            }

            else if(numlen<10)
            {
                alert('Mobile number cannot be less than 10 digits');
                return false;
            }
            else
            {
                //alert('true');
                return true;
            }


        }

        function goodchars(e,goods){    // restrict users from entering letters in the mobile number textbox
            var key, keychar;
            key = getkey(e);
            if (key == null) return true;
            // get character
            keychar = String.fromCharCode(key);
            keychar = keychar.toLowerCase();
            goods = goods.toLowerCase();
            // check goodkeys
            if (goods.indexOf(keychar) != -1)
                return true;
            // control keys
            if ( key==null || key==0 || key==8 || key==9 || key==13 || key==27 )
                return true;
            return false;
        }

        function getkey(e)
        {
            if (window.event)
                return window.event.keyCode;
            else if (e)
                return e.which;
            else
                return null;
        }

        langId = 'EN';
        messageLen = 299;
        message = "";

        function checkCount() {
            //alert('function called');

            if(document.webtosms.message.value.length <= messageLen) {
                message = document.webtosms.message.value;
                document.webtosms.charcount.value = (messageLen - document.webtosms.message.value.length);
            }else {
                document.webtosms.message.value = message;
            }
        }

        function getTemplate(){ // code to populate the drop down and display in the textarea


            var where_is_mytool=document.forms[0].cboTemplate.value;
            var mytool_array=where_is_mytool.split("~");

            //alert(where_is_mytool);
              alert(mytool_array);
            window.document.forms[0].smsa.value=mytool_array[0];
            window.document.forms[0].tmplid1.value=mytool_array[1];
            window.document.forms[0].title2.value=mytool_array[1];
            window.document.forms[0].hidlang.value=mytool_array[2];


            window.document.forms[0].hidcreatedbyval.value=mytool_array[5];


        }
  </script>
  </div>

The above code works absolutely fine once the page is refreshed. I do not want to reload the page once it has already been loaded. Please help.

You need to put all of your javascript in the head section AFTER you include jQuery, but BEFORE you call jQuery mobile.

Your head file should look similar to this (custom JS in second file):

<script src="http://code.jquery.com/jquery-1.7.1.min.js" type="text/javascript"></script>
<script type="text/javascript" src="http://www.example.com/path-to-file/custom-javascript.js"></script>
<script src="http://code.jquery.com/mobile/1.1.1/jquery.mobile-1.1.1.min.js"></script>

UPDATE

On the link to the page, add the attribute data-ajax="false". If you'd like to disable Ajax navigation site-wide, put the following code in your Custom JS file:

$(document).bind("mobileinit", function(){
  $.extend(  $.mobile , {
    ajaxEnabled: false
  });
});

Here's a link to the docs: http://jquerymobile.com/demos/1.1.1/docs/api/globalconfig.html

For me worked put data-ajax="false" on all the links to the page that contains the script.
