JavaScript - Xml Parser Works Locally For Ff But Fails On The Server
Ok, This one has plagued me for some time now. I am parsing an XML file for a search feature. On my local machine, the code below works fine in FF, but when I upload it, I get an error stating y[0] (the root element) is undefined. I think the problem may be with my onload method but I can't be sure.
Code: function importXML() { if (document.implementation && document.implementation.createDocument) { xmlDoc = document.implementation.createDocument("", "", null); xmlDoc.onload = createTable; } else if (window.ActiveXObject) { xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.async=false; xmlDoc.onreadystatechange = function () { if (xmlDoc.readyState==4) createTable(); } } else { alert('Your browser can\'t handle this script'); return; } xmlDoc.load("catalog.xml"); } // and now for the part that fails var y = xmlDoc.getElementsByTagName('data'); var dcount = 0; for (t=0;t<y[0].childNodes.length;t++) { //this is the line where FF reports the error if (y[0].childNodes[t].tagName == "record") { dcount++; } } The xml syntax is as follows Code: <data> <record> <item 1>text</item 1> <item 2>text</item 2> <item 3>text</item 3> </record> <record> <item 1>text</item 1> <item 2>text</item 2> <item 3>text</item 3> </record> </data> I just can't figure out why this works locally and not on the server. IE works fine, but then again it uses the activeXObject method so it should function differently. Similar TutorialsI must make clear that I am not a javascript programmer; I am simply trying to get this script to work on my website. It functions perfectly locally (with all browsers), but after uploading to my website, it shows the controls at the top, but not the content. Below is the code for the FreeMind Flash Browser which can be found he http://freemind.sourceforge.net/wiki.../Flash_browser It requires 2 additional files, flashobject.js and visorFreemind.swf plus the FreeMind file (*.mm) that stores the content. The FreeMind file that has the content displays perfectly on localhost, but not on the website. I have all of these files in the same directory and have double checked everything, but it still doesn't function on my website. I have other flash files and scripts on the same website in other pages that function perfectly.

Here is the link. http://www4.uwm.edu/recsports/ There is supposed to be a rotating slideshow in the header, but it's just a black box. Thanks! Hi, I am working on the following page: http://www.reutin-international.com/redirect.html There is a news script on the right-handside which rotates news items (a kind of scroller). Locally this works without any problems, but once I've uploaded it to the hosting server this doesn't work. There is no javascript error sign. I have double checked with the hosting and they support javascript by default. If anyone has any ideas it'd be appreciated! Thanks! I have a form that passes values to a next step. It has two sub divs that show depending on what's selected from the dropdowns in the top two divs. I'm trying to keep the selected sub divs open if the user hits previous step.

The script works fine when the requested XML file is stored on the same server as the script. The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers? Thanks in advance for any help.

Hi, Following this jQuery slideshow tutorial (Usecase 3 sample, about 2/3 down the page, this is the one without thumbnails): http://www.gcmingati.net/wordpress/w...vwt/index.html I constructed the slideshow: http://backstageweb.net/Salon/slideshowcode.htm ...which works perfectly in browser view locally (FF and IE). When uploaded to the server, however, I've got a static list of photos as you can see. Can someone shed some light on what the problem is? All relevant files are attached (I changed the images to simple colors to get the file size within the attachment limit). Thanks. John Hi, yes I have 2 questions up related to audio! Not sure Javascript is the problem. I am trying 2 completely different methods. Either would be OK if they worked. With this method the audio works fine testing locally in the browser, popping up a window with a helper player BUT when on the site it opens the window which then downloads the mp3 instead of playing it. http://museum.spps.org/pop_up_audio.html This is the script Code: <script> <!-- function wopen(url, name, w, h) { // Fudge factors for window decoration space. // In my tests these work well on all platforms & browsers. w += 32; h += 96; var win = window.open(url, name, 'width=' + w + ', height=' + h + ', ' + 'location=no, menubar=no, ' + 'status=no, toolbar=no, scrollbars=no, resizable=no'); win.resizeTo(w, h); win.focus(); } // --> </script> This is the code for the link text Code: <a href= "uploads/2ndGraders.mp3" rel="nofollow" target="popup" onClick="wopen('uploads/2ndGraders.mp3', 'popup', 350, 150); return false;"> 2nd Graders talk about Museum Magnet</a> hope someone can help. I am not a javascripter, I just hunted down a couple of things that looked like they might work. thanks Mark i still cant ouput correctly this php parse rss: PHP Code: $doc = new DOMDocument(); $doc->load('http://www.lepoint.fr/content/system/rss/a_la_une/a_la_une_doc.xml'); $count_items=$doc->getElementsByTagName("item"); //echo count($count_items); $title=$doc->getElementsByTagName("item")->item(0)->getElementsByTagName("title")->item(0)->nodeValue; foreach($count_items as $value){ echo "<table border='1'><tr><td>".$value->getElementsByTagName('title')->item(0)->nodeValue."</td><td>".$value->getElementsByTagName('description')->item(0)->nodeType."</td></tr>";} using this js code : Code: <style> div#RSS{width: 700px;height: 600px;border:1px solid gray;} </style> <script> PHPscript="<?php $doc = new DOMDocument();$doc->load('http://www.lepoint.fr/content/system/rss/a_la_une/a_la_une_doc.xml');$count_items=$doc->getElementsByTagName('item');$title=$doc->getElementsByTagName('item')->item(0)->getElementsByTagName('title')->item(0)->nodeValue;foreach($count_items as $value){echo '<table border=\'1\'><tr><td>\'.$value->getElementsByTagName(\'title\')->item(0)->nodeValue.\'<\/td><td>\'.$value->getElementsByTagName(\'description\')->item(0)->nodeType.\'<\/td><\/tr>';} ?>" function ClickRSS(){ document.getElementById("link").onclick=ShowRSS } function ShowRSS(){ div=document.createElement("div"); div.id="RSS"; div.innerHTML=PHPscript; document.body.appendChild(div); } window.onload=ClickRSS; </script> <body> <a href="#no" id="link">LINK</a> </body> Hi I would like to write a parser like the one below except I would like it to take characters with the the digits like 345j, 982p0, what would I change to be able to have characters with numbers? Code: ts.addParser({ id: "digit", is: function (s, table) { var c = table.config; return $.tablesorter.isDigit(s, c); }, format: function (s) { return $.tablesorter.formatFloat(s); }, type: "numeric" }); Say that I've got the following XML Code: <document> <block key="block1"> <p>This is a <bold>paragraph</bold></p> </block> <block key="block2"> <p>Additional paragraph</p> </block> </document> Obviously the schematics of this data and the constraints placed upon them can be described using XSD. For example, the following rules would apply: * must be a document element as the top-level parent element * must be at least one block element as a child of document * each block must have a unique key value * blocks can have 1...n p child elements. * p elements can have 0...n bold child elements What I'm looking for is an engine that executes on the client-side (JavaScript / jQuery) that can parse the XSD and flag any errors. In addition I would also need to be able to interrogate the engine in order to determine what are valid child nodes at a particular level of the XML. For example, the following types of queries might be asked of the engine: * Q: Is the overall XML valid? A: yes / no + report * Q: I'm looking at the element block (key="block2"). What are the valid child elements of this element? A: p (1...n). * Q: I'm looking at the element p in the first block (key="block1"). What are the valid child elements of this element? A: #text, bold (0...n). Determining the valid child elements of a particular element is something akin to how Visual Studio e.g. 2010 uses Intellisense. For example, given a schema Visual Studio let's you know what the valid elements are at a particular position as you type enter the XML. Finally I've mentioned XSD / XML above but we do not necessarily have to be constrained to these technologies so alternative ideas will be appreciated equally as well.

Please inform us about it in the forum." ).css({'width':'400px','margin-left':'-200px'}); $( 'div.nogood' ).fadeIn(500, away); function away() { $( 'div.nogood' ).delay(2000).fadeOut(500); }; } }); } else { alert("HUh"); $( 'div.nogood' ).fadeIn(500, away).css({'width':'400px','margin-left':'-200px'});; $('.ui-draggable-dragging').draggable({revert: true}); if (pLvl<$('.ui-draggable-dragging').data('lvl')) { alert("Good"); } else if (pStr<$('.ui-draggable-dragging').data('rstr')) { $('div.nogood').html("Not enough strength.") } function away() { $( 'div.nogood' ).delay(1400).fadeOut(500); }; } } }); }, stop: function(event, ui) { $('div#'+$(this).data('equip')).css({'border':'none', 'background':'transparent'}).droppable("destroy"); } }); n++; i++; } This if comparison if (pLvl>=$('.ui-draggable-dragging').data('lvl') && pStr>=$('.ui-draggable-dragging').data('rstr')) somehow goes through. After the if statement I check the values with the alert but it displays 5 for pLvl and 10 for the draggables data (which are the correct numbers) so can anyone tell me why does this if statement still go through when pLvl is lower? I have a form that is used to insert a new classified ad or to update an existing ad. When the submit button is pressed a javascript function is called to validate the fields. Some of the fields are set as required. If the field is empty ( as form[i].value = '' ) then this sets an error flag and after all fields have been tested will display an alert and each field that has an error will be highlighted in red. This works great when a new ad is being created, but when the ad is being updated, and a required field is erased then it doesn't popup as an error, as if the script is just ignoring it. Here is the code snipit: Code: function submitbutton(mfrm) { var me = mfrm.elements; var r = new RegExp("[\<|\>|\"|\'|\%|\;|\(|\)|\&|\+|\-]", "i"); var r_num = new RegExp("[^0-9\.,]", "i"); var r_email = new RegExp("^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]{2,}[.][a-zA-Z]{2,3}$" ,"i"); var errorMSG = ''; var iserror=0; // set notification background color var warnColor = '#<?php echo $this->error_color; ?>'; // loop through all input elements in form for (var i=0; i < me.length; i++) { // check if element is mandatory; here mosReq="1" if ((me[i].getAttribute('mosReq') == 1)&&(me[i].style.visibility != 'hidden')) { if (me[i].type == 'radio' || me[i].type == 'checkbox') { var rOptions = me[me[i].getAttribute('name')]; var rChecked = 0; if(rOptions.length > 1) { for (var r=0; r < rOptions.length; r++) { if (rOptions[r].checked) { rChecked=1; } } } else { if (me[i].checked) { rChecked=1; } } if(rChecked==0) { errorMSG += me[i].getAttribute('mosLabel').replace(' ',' ') + ' : <?php echo html_entity_decode(addslashes(JText::_('COM_CLASSIFIEDSREDUX_REGWARN_ERROR')),ENT_QUOTES); ?>\n'; // notify user by changing background color, in this case to red me[i].style.background = warnColor; iserror=1; } } if ((me[i].value == '') || (me[i].value.length < 2)) { errorMSG += me[i].getAttribute('mosLabel').replace(' ',' ') + ' : <?php echo html_entity_decode(addslashes(JText::_('COM_CLASSIFIEDSREDUX_REGWARN_ERROR')),ENT_QUOTES); ?>\n'; me[i].style.background = warnColor; iserror=1; } } } if(iserror==1) { alert(errorMSG); return false; } } So, I know there are lots of threads out there about the jQuery validation plugin and people having issues with IE7, but most of them come down to syntax issues with a closing comma or what not. With that said, I have milled over this code of least a full day now and still have no idea why it fails in IE (all versions) http://jsfiddle.net/rM3ej/4/ Can anyone give me some ideas or insight why this would completely fail? Thanks in advanced. i cant get collission detection to work. i tryed but it always caused an infinite loop. heres the code.

But if I try to do the image swap instead of the two commented lines, it doesn't swap. Of course, the image enter1.gif and enter2.gif exist. What am I doing wrong? http://edison.seattlecentral.edu/~dw.../testform2.htm http://edison.seattlecentral.edu/~dw...ude/util-dw.js Could someone check js and tell me how I can get the form to validate it hangs up on password. |
