  • Loading html dynamically using Javascript and PHP

    - by Vafello
    I have the following code: <?php if ($x == 1){ ?> <b>Some html...</b> <?php } else if ($x==2){ ?> <b> Other html...</b> <?php } ?> Now I would like to have two links below (a href) and somehow pass the variable $x (so Link1 passes x=1 and Link2 passes x=2) in order to load the relevant bit of code from if statement. I know I can pass $x using form and then test its value and load required bit of code, but I would like to do it smoothly, without reloading the page. I think that JQuery could help it, but I have no idea how to do it. Any ideas greatly appreciated.

    - by alex
    I need some scripts inside an existing site's scripts.js. This site has been online for ages, and I can not touch the scripts file. I am including it standardly in another page. There are numerous jQuery calls in the scripts file. The place I include it does not have jQuery. I want to void all $() type things. I tried this... $ = function() { }; before I included scripts.js and it didn't seem to work. I am still getting errors like $(document) is undefined Is there a way to void all these jQuery calls? Thanks

  • delete row from result set in web sql with javascript

    - by Kaijin
    I understand that the result set from web sql isn't quite an array, more of an object? I'm cycling through a result set and to speed things up I'd like to remove a row once it's been found. I've tried "delete" and "splice", the former does nothing and the latter throws an error. Here's a piece of what I'm trying to do, notice the delete on line 18: function selectFromReverse(reverseRay,suggRay){ var reverseString = reverseRay.toString(); db.transaction(function (tx) { tx.executeSql('SELECT votecount, comboid FROM counterCombos WHERE comboid IN ('+reverseString+') AND votecount>0', [], function(tx, results){ processSelectFromReverse(results,suggRay); }); }, function(){onError}); } function processSelectFromReverse(results,suggRay){ var i = suggRay.length; while(i--){ var j = results.rows.length; while(j--){ console.log('searching'); var found = 0; if(suggRay[i].reverse == results.rows.item(j).comboid){ delete results.rows.item(j); console.log('found'); found++; break; } } if(found == 0){ console.log('lost'); } } }

  • replace a buch of show/hide with switch/case in javascript

    - by Adam
    Page has menu items that would replace a 'div id=foo_(current menu item)' with 'div id=foo_(selected menu item)' in 'div class=foo' Here's what I've got, and try to keep your breakfast down... $('#t1').click(function() { $('#attorney').show(); $('#insurance,#financial,#estate,#trust,#death').hide(); }); $('#t2').click(function() { $('#insurance').show(); $('#attorney,#financial,#estate,#trust,#death').hide(); }); $('#t3').click(function() { $('#financial').show(); $('#attorney,#insurance,#estate,#trust,#death').hide(); }); $('#t4').click(function() { $('#estate').show(); $('#attorney,#insurance,#financial,#trust,#death').hide(); }); $('#t5').click(function() { $('#trust').show(); $('#attorney,#insurance,#financial,#estate,#death').hide(); }); $('#t6').click(function() { $('#death').show(); $('#attorney,#insurance,#financial,#estate,#trust').hide(); });

  • page transitions using javascript

    - by hasan
    hey, i saw this on a site a couple of days ago and i cant seem to find it again. in any case, this is what was on the site: the page opened regularly when you entered the url. upon clicking one of the links on the page, it "transitioned" to the next page (there was a color change). and the url in the address bar was changed to reflect that. eg: if the background was blue on site.com, when clicking on the about link, the background would change to green and the browser would show site.com/about. and so on. also, if the url entered was site.com/about, the bg would be green and on cliking the home page, the site would transition from green to blue and browser would show site.com im interested in finding out how this was done. searching on google got me the meta-refresh tag, but the ffect was much more complex and worked on all browsers. is there any other method out there?

  • How to Append a div with javascript inside

    - by Damathryx
    I have this <div id="inprog_table"> </div> I tried this to insert var div = document.getElementById('inprog_table'); div.innerHTML = div.innerHTML+ "<div class='row'> <div class='col-xs-7'> "+ $(".row.active .col-xs-7 p:first-child").text()+" </div> <div class='col-xs-2'> "+ $(".row.active .col-xs-7 p:last-child").text()+" </div> <div class='col-xs-2'> 1 </div>" inside inprog_table div. I know it's really wrong, but I don't know how to append all of this.

  • javascript literal initialisation loop

    - by graham.reeds
    I have an object which has several properties that are set when the object is created. This object recently changed to object literal notation, but I've hit a bit of a problem that searching on the net doesn't reveal. Simply stated I need to do this: Star = function(_id, _x, _y, _n, _o, _im, _c, _b, _links) { var self = { id: _id, // other properties links: [], for (var i=0,j=0;i<8;i++) { //<- doesn't like this line var k = parseInt(_links[i]); if (k > 0) { this.links[j++] = k; } }, // other methods }; return self; }; How do I initialise a property in the constructor in object literal notation?

  • Is the javaScript not part of the DOM?

    - by DKinzer
    Why is it that scripts can still function even after the code used to create them is removed from the DOM? I ran into a situation where I wanted to prevent a broken script from running (@see my post). In my attempt to come up with a solution I wrote an extension with the following line (just to see what would happen). //doc is passed here because this script is running as a firefox extension outside //of the document context. $('script', doc).remove(); I assumed that this would remove all the scripts from the DOM, which it did, and that therefore no scripts would run on the page, which is not the case. I would love to know more about what's behind this behavior.

  • Emulate clicking a link with Javascript that works with IE

    - by Tam
    I want to have java script clicking a link on the page..I found something on the net that suggests adding a function like this: function fireEvent(obj,evt){ var fireOnThis = obj; if( document.createEvent ) { var evObj = document.createEvent('MouseEvents'); evObj.initEvent( evt, true, false ); fireOnThis.dispatchEvent(evObj); } else if( document.createEventObject ) { fireOnThis.fireEvent('on'+evt); } } Then call it using: fireEvent(document.getElementById('edit_client_link'),'click'); This seems to work fine for FF but with IE it doesn't work! Any ideas?

  • Providing updating suggestions list with javascript, php and ajax

    - by user1104854
    I'm trying to modify this example on making a live updating list to integrate it with my API. So, instead of using GET on the page with the form, I'd like to send it to that page via a function call. So, here's my form // message.php //function to display the hint sent from gethint.php function message_hint($hint){ echo $hint; } //displays the form for sending messages function send_message_form($to_user,$title,$message){ include 'gethint.php'; ?> <table> <form name = "send_message" method="post"> <td>Send A Message</td> <tr><td>To:</td><td><input type = "text" size="50" name="to_user" id = "to_user" value ="<? echo $to_user; ?>" onkeyup="showHint(this.value)"></td></tr> <tr><td>Title:</td><td><input type = "text" size="50" name="message_title"></td></tr> <tr><td>Message:</td><td><textarea rows="4" cols="50" name="message_details"></textarea></td></tr> <tr><td><input type="submit" name="submit_message"></td></tr> </table> </form> <? } Here's the head of message.php <head> <script> function showHint(str){ var to_user = document.getElementById("to_user").value //to_user is the id of the textbox if (str.length==0){ to_user.innerHTML=""; return; } if (window.XMLHttpRequest){// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); }else{// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function(){ if (xmlhttp.readyState==4 && xmlhttp.status==200){ alert(to_user) //properly displays the name via alert box to_user.innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","gethint.php?q="+to_user,true); xmlhttp.send(); } </script> </head> The page gethint.php is exactly the same, aside from this at the bottom. //echo $response //this was the original output $message = new messages; $message->message_hint($response);

  • Javascript onclick stops working, multiple dynamically created divs.

    - by Patrick
    I have run into a strange problem, i am creating a lot of dynamically divs. And i recently found out that some of my divs doesn't fire the onclick event? All the divs are created using the same template, so why are some not working? Most of the time, its the 4-5 from the bottom. If you click on one of the others and then try again, you might get one of those to trigger. But only sporadically. Code to create the divs: GameField.prototype.InitField = function(fieldNumber) { var newField = document.createElement("div"); if (fieldNumber == 0 || fieldNumber == 6 || fieldNumber == 8 || fieldNumber == 17) newField.className = 'gameCellSmall borderFull gameText gameTextAlign'; else newField.className = 'gameCellSmall borderWithoutTop gameText gameTextAlign'; var instance = this; if (fieldNumber == 6 || fieldNumber == 7 || fieldNumber == 17) { } else newField.onclick = function() { instance.DivClick(fieldNumber); return false; } this.fields[fieldNumber] = newField; this.score[fieldNumber] = 0; return newField; } I added the return false to the click function, but it still behaves strangely. Why are some not triggering? I create around 18 divs / player. But it happens even if i just create one player. Do i perhaps need to cancel the event once i am done with it? (Like the return false; is trying to do)

  • Write to a textfile using Javascript

    - by karikari
    Under Firefox, I want to do something like this : I have a .htm file, that has a button on it. This button, when I click it, the action will write a text inside a local .txt file. By the way, my .htm file is run locally too. I have tried multiple times using this code, but still cant make my .htm file write to my textfile: function save() { try { netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); } catch (e) { alert("Permission to save file was denied."); } var file = Components.classes["@mozilla.org/file/local;1"] .createInstance(Components.interfaces.nsILocalFile); file.initWithPath( savefile ); if ( file.exists() == false ) { alert( "Creating file... " ); file.create( Components.interfaces.nsIFile.NORMAL_FILE_TYPE, 420 ); } var outputStream = Components.classes["@mozilla.org/network/file-output-stream;1"] .createInstance( Components.interfaces.nsIFileOutputStream ); outputStream.init( file, 0x04 | 0x08 | 0x20, 420, 0 ); var output = 'test test test test'; var result = outputStream.write( output, output.length ); outputStream.close(); } This part is for the button: <input type="button" value="write to file2" onClick="save();">

  • JavaScript try/catch: errors or exceptions?

    - by Josh
    OK. I may be splitting hairs here, but my code isn't consistent and I'd like to make it so. But before I do, I want to make sure I'm going the right way. In practice this doesn't matter, but this has been bothering me for a while so I figured I'd ask my peers... Every time I use a try... catch statement, in the catch block I always log a message to my internal console. However my log messages are not consistent. They either look like: catch(err) { DFTools.console.log("someMethod caught an error: ",err.message); ... or: catch(ex) { DFTools.console.log("someMethod caught an exception: ",ex.message); ... Obviously the code functions properly either way but it's starting to bother me that I sometimes refer to "errors" and sometimes to "exceptions". Like I said, maybe I'm splitting hairs but which is the proper terminology? "Exception", or "Error"?

  • Fixing javascript Array functions in Internet Explorer (indexOf, forEach, etc)

    - by Chas Emerick
    As detailed elsewhere, and otherwise apparently well-known, Internet Explorer (definitely 7, and in some instances, 8) do not implement key functions, in particular on Array (such as forEach, indexOf, etc). There are a number of workarounds here and there, but I'd like to fold a proper, canonical set of implementations into our site rather than copy and paste or hack away at our own implementations. I've found js-methods, which looks promising, but thought I'd post here to see whether another library comes more highly-recommended. A couple of misc. criteria: the lib should just be a no-op for those functions that a browser already has implementations for (js-methods appears to do quite well here) non-GPL, please, though LGPL is acceptable

  • Pure HTML + JavaScript client side templating

    - by Dev er dev
    I want to have achieve something similar to Java Tiles framework using only client side technologies (no server side includes). I would like to have one page, eg layout.html which will contain layout definition. Content placeholder in that page would be empty #content div tag. I would like to have different content injected on that page based on url. Something like layout.html?content=main or layout.html?content=edit will display page with content replaced with main.html or edit.html. The goal is to avoid duplicating code, even for layout, and to compose pages without server-side templating. What approach would you suggest? EDIT: I don't need a full templating library, just a way to compose a pages, similar for what tiles do.
