How remove block in dxf file?

Javascript remove problem?

• Hey Everyone, what i am trying to do is everytime a file is uploaded i want a remove button to appear next to it. This works fine. However, the problem i am having is every time i hover over the remove button you get the following names for example if i have 3 files the first file with a remove will say javascript:removeFileInput(f1), the second javascript:removeFileInput(f2),and 3rd javascript:removeFileInput(f3). The problem with this is if i remove the second file the first one will still say f1, but the problem is with the 3rd one. The third one should change to f2 (since removing the second one makes the 3rd become the second one) but instead it still remains f3 and i am wondering how could i make it change to f2 ? the reason i need to be able to do this is because if i try to insert it into my database it gives me an error an asks for f2. Here is the code i have javascript <script type="text/javascript"> var upload_number = 1; function addFileInput() { var d = document.createElement("div"); var l = document.createElement("a"); var file = document.createElement("input"); var text = document.createElement("input"); d.setAttribute("id", "f"+upload_number); file.setAttribute("type", "file"); file.setAttribute("name", "attachment"+upload_number); text.setAttribute("type", "text"); text.setAttribute("name", "description"+upload_number); l.setAttribute("href", "javascript:removeFileInput('f"+upload_n… l.appendChild(document.createTextNode("R… d.setAttribute("id", "f"+upload_number); d.appendChild(file); d.appendChild(text); d.appendChild(l); document.getElementById("moreUploads"). appendChild(d); document.getElementById("totalAttachment… = upload_number; upload_number++; } function removeFileInput(i) { var elm = document.getElementById(i); document.getElementById("moreUploads"). removeChild(elm); upload_number = upload_number - 1 } </script> form <input type="file" name="attachment1" id="attachments" value="" onchange="document.getElementById('moreU… style.display = 'block';" /> Description <input type="text" name="description1 " id="description" value="" /> <div id="moreUploads"></div> <div id="moreUploadsLink" style="display:none;"> <input type="button" value="Attach another file" onclick="javascript:addFileInput();" > </div> <input type="hidden" id="totalAttachments" name="totalAttachments" value="1"> Thank you in advance, Rach

• Answer:

  Since I can't see all of your code, I can't be sure, but the following may give you some ideas about how to approach the problem. The notion would be to call renumber() after calling (or at the end of) removeFileInput(). function renumber() { // convenience reference to doc object var d = document; // collection of all divs in page var divs = d.getElementsByTagName( 'DIV' ); var last = divs.length; // counter for renumeration var count = 1; for (var i = 0; i < last; i++) { // reference to current div to examine var div = divs[i]; // if the id starts 'f', look deeper if ('f' == div.id.charAt( 0 ) ) { // chop the leading 'f' - remainder COULD be the // previous value of the upload number var upNum = div.id.substring( 1 ); // if the div has a child with a name like 'description' // with a suffix like its own, treat this as a 'hit' if (hasChildNamed( div, 'description', upNum ); { // new, renumbered div id var dId = 'f' + count; // new, renumbered text name var tName = 'description' + count; // new, renumbered file name var fName = 'attachment' + count; // get references to the text and file elements var text = getChildByName( div, 'description', upNum ); var file = getChildByName( div, 'attachment', upNum ); // change the id and name attributes text.setAttribute( 'name', tname ); file.setAttribute( 'name', fname ); div.setAttribute( 'id', dId ); count++; // iterate the count } } } } function getChildByName( parent, name ) { // collection of all children of parent var children = parent.childNodes; var last = childNodes.length; for (var i = 0; i < last; i++) { var child = childNodes[i]; // if any child has the right name, return a // reference to it, exiting immediately if ( name == child.name) { return child; } } // none found above - return null return null; } function hasChildNamed( parent, name ) { return null != getChildByName( parent, name ); }
