Function refresh load is having this line,

document.getElementById("frmmonthly").reset();

which is resetting your form values.

If I want to return textbox value after it execute ajax code how can i return it?

sushil bharwani Over a year ago

i did not understood your comment please add details of what do you mean by "want to return textbox value"

pranali Over a year ago

Its totally different from above question. Right now i am doing a task on other page where i did serch engine optimization. In that when i type a letter i matches word in database and shows the result like google. but after that when i filter it, it removes all the data in that text box which i want to pass on other page. So that data i want to return.

pranali Over a year ago

The javascript which i used is as below... <script type="text/javascript"> $().ready(function() { $("#users").autocomplete("get_course_list2.php", { width: 260, matchContains: true, mustMatch: true, //minChars: 0, //multiple: true, //highlight: false, //multipleSeparator: ",", selectFirst: false }); $("#users").result(function(event, data, formatted) { //alert(val(data[0])); $("#txt_sid").val(data[1]); //alert(val(data[1])); }); }); </script>
