JavaScript - Add Lots Of Tag Attributes With Javascript
I attempting to set attributes for all tags of a particular type....
I have a bunch of thumbnails <img> tags; when I wand over them I would like to show the corresponding large image with a script but the tags require onMouseOver events. I really don't feel like adding a bunch of onMouseOver="myShowScript" attributes to every img tag manually... my scripts aren't working... partly because I'm a newbie... I'm sure there is some fundamental concept about java and html I don't get... here's ONE of the versions that doesn't work.. I've tried a few things but I'm open to scrapping everything for a better way... I appreciate any direction you can offer... Code: function addAtts(){ var numberOf = document.getElementsByTagName("img"); for(i = 0; i < numberOf.length; i++){ numberOf[i].onMouseOver="myShowScript()"; } } Similar Tutorialshow about getting the attributes of the a tag? href and title and the innerhtml (actually the innerhtml has space on both ends)
Hi Guys, I'm new at JS. I need to remove TR elements from parent table but the problem is there are no table ID/Name Is it possible to perform it?

I want to move a div around a page, and I do this by getting the original top and left values of a div, and then change them. But the problem is getting the original values; I checked online and thought that this would work: Code: var chart = document.getElementById(charDiv).style.top; var charl = document.getElementById(charDiv).style.left; alert('char_t:' + chart + ' char_l:' + charl + 'charDiv:' + charDiv); charDiv is passed into the function (its the id of the div I want to move). I know that charDiv has a value by looking at the values of the alert() statement, but the values of chart and charl are empty. The alert simply outputs char_t: char_l: charDiv: charOne any help would be appreciated Hi everyone, I'm currently in the process of making a spreadsheet like webpage and it all working fine... However I have been using setAttribute and removeAttribute in order to dynamically change a table cells onclick property. This of course does not work in IE7 etc and I've been banging my head against a brick wall trying to come up with a solution that will work in all browsers but I just can't seem to get it to work with using methods such as... Code: document.getElementById(myElementId).onclick = scriptToRun; document.getElementById(myElementId).attachEvent('onclick',scriptToRun); I get all sorts of not implemented, type mismatch errors when I try to use the above. Below is the setAttribute code which works. Code: document.getElementById("task_" + colName + studentId).setAttribute("onclick","showTaskDropDown('task_" + colName + studentId + "','" + studentId + "','" + colName + "','" + value + "','" + maxValue + "','" + trafficMaxValue + "','" + taskNumber + "')"); If anyone can see why the other methods aren't working and can provide a solution I'll be extremely greatful! hello Sir/Mam i have a piece of code here that creates a dynamic form.. Code: <script type='text/javascript' language='javascript'> <!-- function createTextbox(){ var textboxtag = document.createElement("input"); textboxtag.setAttribute("name","username"); document.getElementById("form1").appendChild(textboxtag); } --> </script> <body> <div id='div1'> <button name='textbox' onclick='createTextbox()'>Textbox</button> </div> <div id='div2'> <form id='form1' action='#' method='post'> </form> </div> </body> this code sets the "name" attribute to "username" automatically.. my problem is how to set the name attribute manually by the user after the dynamic textbox is created.. just like in visual basic where after you create a form e.g button or textfield, theres a side pane where you can change attributes like name, value, etc.. tnx for the time reading my post..sorry for my poor explanation of the problem..im new in javascript and trying to learn it all by myself.. I am looking to get a loop which runs through a series of divs (each with an attribute called "position" followed by 5 comma separated values). for each of these divs i need the 5 comma separated values (from position) to be assigned to variables. I have the rest of the code sorted out i just cannot get the original variables. Examples: divs look like this... Code: <div position="100,100,50,50,1"></div> There are no limits on the number of these divs but there will never be 0. What i want is something to look like this. For each div, var s = string of attribute (position) values (output:a,b,c,d,e) split string to create var a = a var b = b var c = c var d = d var e = e I from those 5 vars can do what i need. and i know that vars a,b,c,d,e,s will all be overwritten in when it comes to the next div... that is planned. Which is considered best practice? Code: <div onmouseover="doThis();"> myDiv.onmouseover = doThis; myDiv.addEventListener("mouseover",doThis,false); ...or something else? how to search through siblings for shared attributes I have a a long list of links and I suppose Im going to apply a number of classes to each one [describing a number of attributes for each] and I want to do a conditional search probably in javascript/jquery so that when i hover over one of the links I highlight its relatives - those that have the same attributes. What Im having trouble wrapping my head around is the idea of classes to ID these custom attributes. The attributes are coming from a database converted to XML. In my Javascript I essentially want to say that for each link should the user mouseover or mouseclick for each of its sibling links if its sibling link share its attributes style or highlight these compliant siblings a certain way how do I do the 'if statement' without spelling out every possible attribute entry? I know in plain OOP Java how I could test for this but in that scenario I have access to these entries as fields in an object's instantiation. Help? thanks so much in advance Hi All I have a piece of script which makes a div slide out from the side of the screen with information on it. I can change the innerHtml etc no problem, but i have a problem with change .style attributes dynamically. My code: Code: var mystring = "height:500px"; var keyVal = mystring.split(":") var slidingDiv = document.getElementById('slidingDiv'); slidingDiv.style.keyVal[0] = keyVal[1]; As you see above i get a value which i need to split() to get the key and value to use. So what i would like to see is: Quote: slidingDiv.style.height = 500px; But it does not work, as there is no such function as slidingDiv.style.keyVal[0]; How do i change this? I hope I've explained this thoroughly enough. Please ask if i need to explain further. Regards Marinus I'm not really much of a javascript programmer, but I occasionally use javascript that I've found here and there. But I'm unable to find anything that helps me in what I'm trying to do now. I regularly use a snippet of code that pops up a small window to display an image or a very small html file. Using the window.open() function, I'm able to disable scrolling, resizing, etc., and size it to my needs. I'll have a window.close link somewhere on the page. But in my current project, my customer's page has several links related to other companies. When you click on the link, an that company's ad pops up in a small window. At this point, the viewer can simply close the window, or they should be able to click on the ad and be taken to that company's website. I'm able to have it close the window and open that new url in the parent browser window, but my website customer doesn't want their site to go away. They want the new company's website in a new window. Or I can simply NOT close the popup window, but now the new company's website is in a relatively small browser window, unable to scroll, resize, etc. Is there a way for me to somehow modify an existing window with an onclick directive - something similar to the window.open() function, OR open a new browser window with window.open() AND close the popup window? If I haven't made myself clear, let me know and I'll try to explain myself better. Thanks in advance for any help. Hi, I'm not even sure if that's the issue here, but I've isolated it and all the other code is working, so what I'm thinking is that if this: Code: function togglePoly(poly_num) { if (document.getElementById('poly'+poly_num)) { if (document.getElementById('poly'+poly_num).checked) { gpolys[poly_num].show(); } else { gpolys[poly_num].hide(); } } } function createClickablePolyline(poly, html, label) { gpolys.push(poly); var poly_num = gpolys.length - 1; if (!html) {html = "";} else { html += "<br>";} if (html) { GEvent.addListener(poly,'click', function(point) { if (!point) point = poly.getVertex(Math.floor(poly.getVertexCount()/2)); map.openInfoWindowHtml(point,html); }); } label = "<a href='javascript:GEvent.trigger(gpolys["+poly_num+"],\"click\");'>"+label+"</a>"; // add a line to the sidebar html sidebar_html += '<input type="checkbox" id="poly'+poly_num+'" checked="checked" onclick="togglePoly('+poly_num+');">' + label + '<br />'; } document.getElementById("sidebar").innerHTML = sidebar_html; works here to hide/show a line, then this: Code: function show(category) { for (var a=0; a<gpolylines.length; a++) { if (gpolylines[a].mycategory == category) { gpolylines[a].show(); } } for (var i=0; i<pts.length; i++) { if (pts[i].mycategory == category) { pts[i].show(); } } } function hide(category) { for (var a=0; a<gpolylines.length; a++) { if (gpolylines[a].mycategory == category) { gpolylines[a].hide(); } } for (var i=0; i<pts.length; i++) { if (pts[i].mycategory == category) { pts[i].hide(); } } } // this variable will collect the html which will eventually be placed in the sidebar function togglePoly(category) { if (document.getElementById(category)) { if (document.getElementById(category).checked) { show(category); } else { hide(category); } } } function createClickablePolyline(poly, html, name,category) { gpolys.push(poly); var poly_num = gpolys.length - 1; var category = lines[a].getAttribute("category"); midLineArrows(pts, category); GEvent.addListener(poly,'click', function(point) { if (!point) point = poly.getVertex(Math.floor(poly.getVertexCount()/2)); map.openInfoWindowHtml(point,html); }); // add a line to the sidebar html label = "<a href='javascript:GEvent.trigger(gpolys["+poly_num+"],\"click\");'>"+label+"</a>"; sidebar_html += '<input type="checkbox" id="'+category+'" checked="checked" onclick="togglePoly('+category+');">' + label + '<br />'; } document.getElementById("sidebar").innerHTML = sidebar_html; should work here to show/hide lines and arrows the difference of course being that the first code uses poly_num, which is taken directly from the Code: var poly_num = gpolys.length - 1; code (because it only needs to show/hide one line at a time) whereas the second uses the xml attribute "category" from here Code: var category = lines[a].getAttribute("category"); because it's attempting to hide and show a line with arrows on it (the arrows being in the pts array), both of which share the category attribute. It's not throwing up any major errors, but it's not working, either... any suggestions would be great... thanks in advance... Hi, I'm having trouble with some flash players that don't abide by the style attribute of the div they're created in using Javascript. When the flash-players' source is hard-coded into the page source they render fine, but the more players, the more bloat as you can see in the source of the original page. Any help?

I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael Hi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js. But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html. Can any one please let me know how i can make it work in chrome?. Am i missing something here?. Hi Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled! I create the following code but it did not work <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> <script language="JavaScript" type=""> function changeColor(){ document.bgColor = "Gray"; } </script> </head> <body> <script language="JavaScript" type="text/javascript"> var person = ""; person = prompt('What is Your Name:'); if (person == "Foo") { document.write("<h1 />Welcome " + person); document.bgColor = "Yellow"; } else { document.write("<h1 />Access Denied!!!!"); document.bgColor = "Red"; document.getElementById("gree").disabled = true; } </script> <div> <p/><input id="gree" type="button" value="Gray " onClick="changeColor();"> </div> </body> </html> as you can see I used the: document.getElementById("gree").disabled = true; but it did not work , could you please give an idea how I can solve this problem? Thanks Hey, I've got to make the values of some textboxes change the co-ordinates of my sprite on a canvas and havent a clue on how to do it, Here is my form with the two textboxes and submit button: <form> x: <input type="text" name="x" /><br /> y: <input type="text" name:"y" /><br /> <input type="submit" value="Submit"/><br /> </form> And i need it so that they change the values of these: //this shows where my sprite will start on the canvas var block_x; var block_y; searched the internet for hours and cant really find anything i understand or works. any help is much appreciated I got an index.php Code: <html> <form action="bacakomik.php" method='post'> <select name="kodekomik"> <option value='../komik1/|23'>Judul Komik1</option> <option value="../komik2/|20">Judul Komik2</option> <option value="../komik3/|10">Juduk Komik3</option> <option value="../komik4/|20">Judul Komik4</option> </select> <input type="submit" /> </form> <?php echo ('<select>'); echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>'); echo ('</select>'); ?> </html> As you can see, each of the option brings specific value "../komik1/|23" komik1 is a directory | is a delimiter 23 is the pages in one chapter and can be considered also as how many images are there on a specific directory This is my bacakomik.php Code: <?php $dirkomik = $_POST['kodekomik']; $exploded = explode("|", $dirkomik); echo ($exploded[0]); //picture directory echo ("<br>"); echo ($exploded[1]); //total page in the comic $pagecount = (int)$exploded[1]; //Take last posted value, process it right away echo ('<FORM name="guideform"> '); echo ('<select name="guidelinks">'); $i=1; do { echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>'); $i= $i+1; }while($i <= $pagecount); //Printing option and select echo ("</select>"); ?> <input type="button" name="go" value="Go!" onClick="document.getElementById('im').src=document.guideform.guidelinks.options[document.guideform.guidelinks.selectedIndex].value+'.png';"> </FORM> <img src="img0.jpg" id="im"> With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this? I believe that the fix should be somewhere on input tag inside OnClick, or do you know where? Anyway, I found this on the net http://p2p.wrox.com/php-faqs/11606-q...avascript.html Please help me to those who can... I want to insert this js snippet Code: function addText(smiley) { document.getElementById('message').value += " " + smiley + " "; document.getElementById('message').focus(); return false; } to a loaded iframe with name&id chtifrm. I can access it & change embed something in its html via using something like: Code: $(parent.chtifrm.document.body).append('<div id=\"smly\" style=\"cursor:pointer;float:left;top:200px;display:none;position:absolute;\"><\/div>'); .... Code: parent.chtifrm.document.getElementById('chatbox_option_disco').style.display == 'none' but how do I insert js in the head of loaded iframe? |
