Checking file exists or not using javascript??

sourabh1989 · 10-03-2012, 08:31 AM

i want to check that if a path to a file is given and we want to check that the file is present there or not in that directory..??

Below is my html snippet in which i am passing my path as argument in javascript function written in html header section..

Code:

<li><a onclick="db_mcmm('../report_data_fe_nldm_completeness/DB_existence_PVT_report.html');"><h3><u>DB NLDM MCMM</u></h3></a></li>

Javascript function written in header section is as follows :

Code:

<script ="text/javascript">
  
   function db_mcmm(value) {
     var mcmm_file=document.getElementById('content');
     mcmm_file.innerHTML= "<iframe src=" + value + " width=\"79%\" height=\"600px\"></iframe>";
   }
  </script>

Is it possible to check if the file is present in that specified path directory...

Hi,

First, take the onclick handlers out of your HTML. It's bad practice.

Update your links to look like:

Code:

<a class="load_inline" href="../report_data_fe_nldm_completeness/DB_existence_PVT_report.html"><h3><u>DB NLDM MCMM</u></h3></a>

(ie: give them a class of "load_inline", and put the file that you want loaded in the href attribute).

Now put this in your document <head>

Code:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
	$('.load_inline').on('click', function(event){
		event.preventDefault();
		$('#content').load( $(this).attr('href'), function(responseText, textStatus, XMLHttpRequest){
			if ('success' != textStatus) {
				$("#content").html("Sorry, an error occurred");
			}
		});
	});
});
</script>
