    <p>I am developing a ajax upload with progress bar, if the file input isn't multiple there are no problem but I want to develop a multiple ajax upload and for this reason I create a "for" loop until number of files that user has selected.</p> <p>When the function enters here the value of indice is the value of len variable, why does this happen?</p> <pre><code> myXhr.upload.addEventListener('progress', function(e) { progressHandlingFunction(e, '.prog'+(indice)) }, false); </code></pre> <p>The complete code:</p> <pre><code>&lt;script type="text/javascript"&gt; $(document).ready(function(e){ $('#uploader').submit(function(){ var inpf = document.getElementById('files'); var len = inpf.files.length; //console.log(inpf, len);return false; for(var i=0; i&lt;len; i++){ var indice = i; $('div').append('&lt;progress class="prog'+i+'" value="0"&gt;&lt;/progress&gt;&lt;br /&gt;'); var formData = new FormData(); formData.append('image', inpf.files[i]); $.ajax({ url: 'upload1.php', //server script to process data type: 'POST', xhr: function() { // custom xhr var myXhr = $.ajaxSettings.xhr(); if(myXhr.upload){ // check if upload property exists myXhr.upload.addEventListener('progress', function(e) { progressHandlingFunction(e, '.prog'+(indice)) }, false); // for handling the progress of the upload } return myXhr; }, //Ajax events //beforeSend: beforeSendHandler, success: function(data){ completeHandler(data, '.prog'+i); }, //error: errorHandler, // Form data data: formData, //Options to tell JQuery not to process data or worry about content-type cache: false, contentType: false, processData: false, }); } return false; }); }); function progressHandlingFunction(e, klass){ if(e.lengthComputable){ $(klass).attr({value:e.loaded, max:e.total}); } } function completeHandler(data, klass){ $(klass).attr({value:0}); } &lt;/script&gt; </code></pre> <p>Here you have the jsFiddle with the example: <a href="http://jsfiddle.net/Pgq9s/" rel="nofollow">http://jsfiddle.net/Pgq9s/</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
