JavaScript - Js Activates Php File Fails In A Loop
I used the js function httpRequest to activate php files.However, when I use it in a loop, it works only for the last loop, can anyone help me with this?
I had two files:try.php and try1.php /******try.php******/ <script type='text/javascript'> function httpRequest(reqType,url,asynch,respHandle){ if(window.XMLHttpRequest){ request = new XMLHttpRequest(); } else if(window.ActiveXObject){ request = new ActiveXObject("Msxml2.XMLHTTP"); if(! request){ request = new ActiveXObject("Microsoft.XMLHTTP"); } } if(request){ if(reqType.toLowerCase() != "post") { initReq(reqType,url,asynch,respHandle); } else { var args = arguments[4]; if(args != null && args.length > 0) { initReq(reqType,url,asynch,respHandle,args); } } } else { alert("your brower doesn't support this request!"); } } function initReq(reqType,url,bool,respHandle){ try{ request.onreadystatechange =respHandle; request.open(reqType,url,bool); if(reqType.toLowerCase () == "post"){ request.setRequestHeader("Content-Type","application/x-www-form-unlencoded;charset=UTF-8"); request.send(arguments[4]); } else { request.send(null); } } catch ( errv ){ alert("cann't connect to server" + "error message: " + errv.message); } } </script> <script type='text/javascript'> var numarr; function updateStatus(num){ var _url='try1.php?id='+num; httpRequest('GET',_url,true,changeDisplay); } function changeDisplay(){ numarr=request.responseText; document.getElementById('id_'+numarr).innerHTML='changeDisplay'; } </script> <?php $num=array(0,1,2,3,4,5); foreach($num as $value){ ?> <div id='id_<?php echo $value;?>'> this is <?php echo $value;?>; </div> <script type='text/javascript'> updateStatus('<?php echo $value; ?>'); </script> <?php }?> /***try1.php***/ <?php echo $_GET['id']; /************/ the result is: /***result***/ this is 0; this is 1; this is 2; this is 3; this is 4; changeDisplay However, the expected result is: changeDisplay changeDisplay changeDisplay changeDisplay changeDisplay changeDisplay Similar TutorialsHere is the PHP: PHP Code: <?php if (($totalRows_getDie = mysql_num_rows($getDie)) != NULL) { echo "Die Category: <select name='DieCatId' class='dropMenu' id='DieCatId' onchange='jobDieChange(this.value)'> <option value='NULL'></option>"; do { echo "<option value='".$row_dieCatList['DieCatID']."'"; if (!(strcmp($row_dieCatList['DieCatID'], $row_getDie['DieCatID']))) {echo "selected=\"selected\"";} echo ">".$row_dieCatList['DieCatDesc']."</option>"; } while ($row_dieCatList = mysql_fetch_assoc($dieCatList)); $rows = mysql_num_rows($dieCatList); if($rows > 0) { mysql_data_seek($dieCatList, 0); $row_dieCatList = mysql_fetch_assoc($dieCatList); } echo "</select> <a href='popup.php?getpage=dieins' onclick='window.open(this.href, 'popupwindow', 'width=770,height=675,scrollbars,resizable'); return false;'>Add Die</a><br />"; echo "Die: <select name='DieID' class='dropMenu' id='DieID'>"; if ($totalRows_getDie != 0) { echo "<option value='".$row_getDie['DieID']."'>".$row_getDie['DieDesc']."</option>"; } echo "</select><br />"; echo "<input type='hidden' name='DiecutID' value='".$row_getDie['DiecutID']."' />"; } ?> And the JS: Code: var xmlhttpJDie; function jobDieChange(str) { xmlhttpJDie=GetXmlHttpObject(); if (xmlhttpJDie==null) { alert ("Browser does not support HTTP Request"); return; } var url="/scripts/jobdie.php"; url=url+"?q="+str; url=url+"&sid="+Math.random(); xmlhttpJDie.onreadystatechange=JobDieGet; xmlhttpJDie.open("GET",url,true); xmlhttpJDie.send(null); } function JobDieGet() { if (xmlhttpJDie.readyState==4) { document.getElementById("DieID").innerHTML=xmlhttpJDie.responseText; } } In all browsers except IE, it works fine, but IE gets a Script error and won't update the second select. I've gone over this so many times I'm cross eyed! If someone could please help me figure out why IE doesn't like this I would appreciate it. Thank you! 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; } } This is the code part that fails it's if check. Code: while (n<=30) { var slot='#slot'+n; $( slot ).data({no: n, id: itemId[i], name: itemName[i], equip: itemEquip[i], lvl: itemLvl[i], bonus: itemBonus[i], rstr: itemRStr[i], rdef: itemRDef[i]}); $( slot ).draggable({ handle: slot, stack: slot, revert: "invalid", snap: "div#"+itemEquip[i], snapMode: 'inner', start: function(event, ui) { $('div#'+$(this).data('equip')).css({'border': '2px dashed #0066CC', 'background': 'rgba(255,255,255,0.2)'}) .droppable ({ drop: function(event, ui) { if (pLvl>=$('.ui-draggable-dragging').data('lvl') && pStr>=$('.ui-draggable-dragging').data('rstr')) { alert(pLvl+", "+$('.ui-draggable-dragging').data('lvl')); $('.ui-draggable-dragging').css({'display':'none'}); $('div#'+$('.ui-draggable-dragging').data('equip')).html ( "<img src='items/equipped/"+$('.ui-draggable-dragging').data('name')+$('.ui-draggable-dragging').data('id')+".png' />" ) $.ajax({type:"GET", url:"items/change.php", data:"id="+$('.ui-draggable-dragging').data('id')+"&no="+$('.ui-draggable-dragging').data('no'), cache:false, timeout:5000, error: function() { $('div.nogood').html ( "There was an error. 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 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 divs stay open in FF but not in IE.

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. This code is a bit full on, but it works in IE. I am not suspecting the document.write part, but can anyone tell me why this code fails in Firefox? I think it might be the focus parts in red. Is it not right for FF?

This external file does a lot of other stuff besides returning a number. Now here is my problem.. Somewhere in my html file I need to call the showslide function. I tried doing that with this: Code: <script language ="Javascript" src="upload/3weg_slider.js"> document.write(showslide()); </script> But it doesn't return anything, when I place an alert line within the function it doesn't show up either. What am I doing wrong here? Hello, I have the following code that, among other things, should validate US telephone numbers with format: "(800) 800-8000" with hyphen, parenthesis and spaces optional. The regexp is: /^\(?(\d{3})\)?[- ]?(\d{3})[- ]?(\d{4})$/ My main problem is that it validates also numbers like 800 or 800000000000000 etc. The code works perfectly on test pages but not on my website. Something similar happens also for the zipcode. Can someone please tell me what could be wrong? Thanks!

I am using an image galery script written by another person - frogjs (http://www.puidokas.com/portfolio/frogjs/) This script is showing current pic in the middle of the screen and next/previous little tumbnails on right/left sides of the current. When you click the next pic, current pic is zoomed out to the left and next pic is zoomed in to the middle, then replaced by a full-size pic. Then a new tumbnail appears on the place of the next pic you clicked. Zooming and stuff is done with another thirdparty script "effects" (script.aculo.us effects.js v1.7.0) My problem is, the actual next tumbnail is not being shown until the big image is preloaded for this thumbnail. This is done to make it look smooth. So, when i click "next" picture, the next picture is shown, but switching to the following one is delayed until that following one is actually loaded. It is done by making an imgpreloader=Image() object and setting imgpreloader.onload to a function, then setting imgpreloader.src to the big image path. The big image then is supposed to be automatically loaded by browser. When its done, an onload event should fire and that should execute the function that shows the thumbnail for the big picure. Problem is, sometimes the onload event won't happen! And since it wont happen, my gallery will "stall" - it will never show next thumbnail and never allow to continue viewing. And if i show next thumbnail immediately, the next picture would be shown partially and that does not look good. Moreover, i've seen numerous image galeries on numerous sites and all of them seem to work with onload because i only see the image when its loaded, until that i see some "wait" or "grey screen" thing. Never had a problem with those stalling. Problem happens mostly with Opera and Chrome and happens seldom with IE. So, question is, do you probably know what can prevent browsers from firing and OnLoad event or from loading a picture when its suppied as an src for an Image() object? Do you know a workaround that can "poke" the browser to remind it to get the damn picture again and not to stall. Im trying to do a vertical movment of banner to follow the to scrolling screen <script type="text/javascript"> var ban = document.getElementById("left_ads"); var scrn = document.getElementById("bodyinfo"); if (ban.style.top < scrn.offsetTop) { ban.style.top += 1; } if (ban.style.top > scrn.offsetTop) { ban.style.top -= 1; } </script> whe <div Id="left_ads"></div> <body ID="bodyinf"> and in stylesheet: #left_ads{ position: absolute; top: 0px; } but the veriables ban and scrn dont get the value and they are bull so all this fails. using IE+5 Whats wrong plz 10X Tal Ok, so I'm working on a What-You-See-Is-What-You-Get editor, and it works flawlessly - with standards. I'm trying to work out bugs it has with IE, this one is particularly tricky: When the page loads, the editor should be inialized, and the inner HTML of the body of the iframe should set to specified text. This seems to work fine in standards-compliant browsers - Webkit, Firefox. But nothing is written to the body when when the page loads in IE, here's the gist of the code for reference: Code: function loadText(){ document.getElementById("edit").contentWindow.document.body.innerHTML = "predefined text"; } window.onload = loadText; The oddest part, is if I come from a new page to the editor in IE, the text doesn't appear. But when I refresh in IE, the text appears for a split second and disappears. Any help on this matter is greatly appreciated! 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. Image of the output: http://i.imgur.com/jqzhJxb.png What I'm trying to do, is pass an object by reference so that I can use it in other scripts, and allow the current script to change the object's value when appropriate. What's happening: It passes correctly, you can see that my var_dump of the object before the function call is 30. After the function call, it becomes 60. Also, it writes "now60" to the document as instructed. When I call the function the second time, it does nothing. No error, no repeat of writing now60 to the document, etc. And in the last var_dump, which is after the second function call - you can see that the value remained 60. Why? Thanks for your help! Code: PHP Code: var quickChallengeTimer = {timer:30}; var quickChallengeQuestion; var quickChallengeAnswer; var quickChallengeResponse; function quickChallenge(quickChallengeTimerfunc, quickChallengeQuestion, quickChallengeAnswer) { if (typeof quickChallengeResponse == 'undefined') { switch (quickChallengeTimerfunc.timer) { case 30: quickChallengeTimerfunc.timer = 60; quickChallengeResponse = 'undefined'; document.write("now60"); break; case 60: quickChallengeTimerfunc.timer = 120; quickChallengeResponse = 'undefined'; document.write("now120"); break; default: document.write("Error"); break; } } console.dir(quickChallengeTimerfunc.timer); } var_dump(quickChallengeTimer); quickChallenge(quickChallengeTimer); var_dump(quickChallengeTimer); quickChallenge(quickChallengeTimer); var_dump(quickChallengeTimer); i'm working with a javascript on a drupal website, but the saving function seems to work only as soon as i click 2 times on the "save" button. the code that fires the function is: Code: var param ="&usuario="+usuario+"&nivel="+nivel+gano+porc_gano+gasto+porc_gasto+tengo+porc_tengo+debo+porc_debo+plazo_debo; var s = document.createElement("script"); s.type = "text/javascript"; s.async = true; s.src = direccion_servidor +"setMisDatos?callback=respuestaGuardarMisDatos¶m="+encodeURIComponent(param); h = document.getElementsByTagName("script")[0]; h.parentNode.insertBefore(s, h); i got the parentNode.insertBefore code from google (the same they use in google analitycs), but still i get error (specifically when he has to do the parentNode.insertBefore part (earlier it was only appendChild, but used to give me the same kind of error. Are the spaces a problem in this sense? Or there might be a better solution? because if i click the second time it enters the setMisDatos function and then works 100%. This is really driving me crazy, can anybody help me? |
