Hi, I'm relativly new to JS and brand new to the forum so you might need to dumb down your replys for my slightly lacking knowledge. That being said I do have a very solid grasp of html, css and am getting there with JS and its various frameworks. I'm integrating wordpress into an existing site for a friend and currently have the main blog page appear in a DIV. This is the best way to integrate in this case due to many reasons mostly of way the site is constructed. Code: <div class="scroll-pane" id="scrollbox"> WORDPRESS BLOG </div> My issue is that links within that DIV, in the blog, when clicked redirect the page. The simple answer to this would be to have them just open in a new page, which I can easily do with the below code. Code: function Init() { // Grab the appropriate div theDiv = document.getElementById('scrollbox'); // Grab all of the links inside the div links = theDiv.getElementsByTagName('a'); // Loop through those links and attach the target attribute for (var i=0, len=links.length; i < len; i++) { // the _blank will make the link open in new window links[i].setAttribute('target', '_blank'); } } window.onload = Init; But what I'd rather it do is have any link clicked inside the DIV to reload in that same DIV, similar to an iframe, but obviously without using an iframe, due to it's compatibility issues. Is this possible by editing the above code? If not what do I need? Thanks in advance for any help! Hi guys, My brain is not working. May be I need a coffee break. I need your expertise. Below is the code holding the textarea. Look for the element with the id : themessage Code: <table width="100%" border="0"> <tr><td rowspan="4"><input type="button" name="send_email" id="send_email" style="height:50px; width:100px;" value="SEND" onClick="return err_check();" /></td><td><span class="que">From : </span></td><td colspan="3"><?php echo $from_email; ?><input type="hidden" name="from_mail" id="from_mail" value="<?php echo $from_email;?>"/><input type="hidden" name="camp_id" id="camp_id" value="<?php echo $camp_id;?>"/></td></tr> <tr><td><span class="que">To : </span></td><td colspan="3"><input name="to_email" id="to_email" style="width:250px;" /></td></tr> <tr><td><span class="que">CC : </span></td><td colspan="3"><input name="cc_email" id="cc_email" style="width:250px;"/></td></tr> <tr><td><span class="que">Subject : </span></td><td colspan="3"><input style="width:300px;" name="subject" id="subject" /></td></tr> <tr><td rowspan="1" colspan="2"> </td><td><input type="checkbox" name="ori_pdf" id="ori_pdf" /> PDF Quotation</td><td> </td><td> </td></tr><tr><td colspan="2"><span class="que">Credit Application</span></td><td><input type="checkbox" name="corporate" id="corporate"/>Corporate</td><td><input type="checkbox" name="individual" id="individual" />Individual</td><td><input type="checkbox" name="cash" id="cash" />Cash Account</td> </tr> <tr> <td colspan="2" rowspan="3"></td><td><input type="checkbox" name="tabloid" id="tabloid" />Tabloid Example</td> <td><input type="checkbox" name="broadsheet" id="broadsheet" />Broadsheet Example</td></tr> <tr><td><input type="checkbox" name="colmt" id="colmt" />Column Sizes Tabloid</td> <td><input type="checkbox" name="colmb" id="colmb" />Column Sizes Broadsheet</td></tr> <tr><td><input type="checkbox" name="maps" id="maps" />Maps / Distribution</td><td colspan="2" align="right">External Attachments <input id="upload_file" name="upload_file" type="file"/> </td></tr> <tr><td colspan="2"><span class="que">Message :</span></td><td colspan="3"> <textarea id="themessage" name="themessage" rows="15" cols="80" style="width: 100%"> </textarea> </td></tr> </table> Now on a button click, I'm trying to pass some values which one of them happens to be what ever that is entered in the textarea. For some reason, the stupid JS is not reading. But I think it is me that is stupid, not JS. Below is the code i'm running to get the value. Code: var message = document.getElementById('themessage').value; alert(message); The alert simply returns blank. There is an alert, but no value even where there is text in the text area. Can someone please shed some light on this. pretty please Hi all! I created a form where users are allowed to delete a specific row of data by clicking the "cancel" button from the drop down menu. However, I have a problem deleting my data using the javascript. Apparently, I only able to delete the first row of the data but not for the rest! The following is the code i have: PHP Code: <html> <body style="background-color:#E0FFFF;"> <script language="javascript" > <!-- hide function submitRequest(val) { document.forms[0].submit(); } // end hide --> </script> <?php $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("my_course", $con); $result = mysql_query("SELECT * FROM Courses ORDER BY Year, Sem, CourseCode"); $result1 = mysql_query("SELECT * FROM Courses ORDER BY Year, Sem, CourseCode"); echo "<table border='1' cellpadding='2' cellspacing='0'> <tr> <th>CourseCode</th> <th>CourseName</th> <th>Year</th> <th>Sem</th> <th>Grade</th> <th>Option</th> </tr>"; ?> <?php while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['CourseCode'] . "</td>"; echo "<td>" . $row['CourseName'] . "</td>"; echo "<td>" . $row['Year'] . "</td>"; echo "<td>" . $row['Sem'] . "</td>"; echo "<td>" . $row['Grade'] . "</td>"; echo "<td>"; ?> <?php ?> <form name="form1" action="submitDelete.php" method="post"> <select name="cancel" onchange="submitRequest(this.value);"> <option value=> </option> <option value="<?php echo $row['CourseName'];?>">Cancel</option> </select> </form> <?php echo "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); ?> <br/> <br/> </body> </html> Thanks in advance! I am restarting a thread because as a result of acting on all of the suggestions I have received the nature of the issue has changed. I am trying to create a button and add it to the DOM under IE7. The code works fine under Firefox: Code: var editButton = document.createElement("button"); editButton.name = "editCitation" + rowNum; try { editButton.type = 'button'; } catch(e) { // IE7 throws this exception alert("citTable.js: gotAddCit: unable to set type for <button name='editCitation" + rowNum + "' type=" + editButton.type); } editButton.onclick = editCitation; editButton.appendChild(document.createTextNode('Edit Citation')); td1.appendChild(editButton); I am creating a <button> rather than an <input type=button> because a <button> permits HTML in the button label. Most of my buttons support Alt keyboard shortcuts, so I want to underline the appropriate letter in the label. According to the HTML 4.01 specification, which is as close to a standard as IE7 supports, a <button> can be one of three types: submit, reset, or button, and the default is submit. Since I wish to create a <button type=button> I therefore, at least theoretically, need to be able to set the value of the type attribute. However IE7 throws an exception at that point, although, interestingly, when I interrogate the value of editButton.type in the catch it is set to button. So how do I reliably set the type of a button under IE7? http://jsfiddle.net/FZ44M/3/ Thats my jsfiddle. I'm trying to get the gallerynav to sort the thumbnails based on their class. It does not work at all. I've gone over line by line but I can't see the mistake.

Hi, I'm new to JavaScript and I'm having problem with appending a div node returned from a function. Here's where it crashed: Code: var div=document.getElementById("dashboard_secondary_cat_list"); var s=get_secondary_cat_node(attributes); alert("b4 appendin:"+s); div.appendChild(s); alert("done appendin"); alert("done appendin"); never gets called because the previous line crashes. alert("b4 appendin:"+s); shows: b4 appendin:[object HTMLDivElement] Hello. I'm trying to set up a login formular with PHP and JavaScript/jQuery. Currently it sends an alert box, if some information are wrong. If correct, it refreshes the page, and everyone's happy. However, I noticed upon the first visit, I cannot log in. Lets say I go to www.mysite.com and try to login, it displays a blank alert box, when it's suppose to display the username, that I supplied, and is wrong... however, it's blank. BUT! If I go to another page and login with false informations, an alert box with the wrong username pops up - if I login with correct informations, it works. How come it won't work on first visit? What am I doing wrong here? Pressing F5 won't work either - I have to manually switch to another page for it to work. Any suggestions and ideas are welcome and appreciated. I'll supply the codes necessary for anyone to help me, but at this point I'm completely blank on which of my codes may be the problem. EDIT - IMPORTANT INFORMATION! Now THIS is weird! I just noticed it's because there's not www. in the URL. There has to be www. for it to work, why is this? I forced the client to have www. in the URL with .htaccess, but I'd still like to know, why this problem occurs without it. I'm relatively new to javascript and I'm having some issues in adding linebreaks i.e. working <br> tags via DOM manipulation. An example of where I cant get it to work is included in the function code below. The html file the script is used in contains one div with an id of pfield. If its helpful the full program is available at http://www.templeofmick/wumpus3.htm Code: function printHints() { var vFlags = [0, 0, 0]; //Wumpus, Pit, bat var wFlag = 0; //Use flags to insure each hint isnt printed multiple times var pFlag = 0; var bFlag = 0; var node; var i; var pbreak = document.createElement("br"); var turnP = document.createElement("p"); var idString = ("turn" + turn); turnP.setAttribute("id", idString); document.getElementById("pfield").appendChild(turnP); for (i = 0; i < 3; i++) { vFlags = checkRoom(currentMap[currentRoom][i]); if (vFlags[0] === 1) { wFlag = 1; } if (vFlags[1] === 1) { pFlag = 1; } if (vFlags[2] === 1) { bFlag = 1; } } node = document.createTextNode("You are in room " + currentRoom + "."); document.getElementById(idString).appendChild(node); document.getElementById(idString).appendChild(pbreak); node = document.createTextNode("From here you can travel to room : " + currentMap[currentRoom][0] + "," + currentMap[currentRoom][1] + " and " + currentMap[currentRoom][2] + "."); document.getElementById(idString).appendChild(node); document.getElementById(idString).appendChild(pbreak); if (wFlag === 1) { node = document.createTextNode("The acrid stench of a nearby wumpus fills your delicate nostrils."); document.getElementById(idString).appendChild(pbreak); document.getElementById(idString).appendChild(node); } if (pFlag === 1) { node = document.createTextNode("The whistling of the wind indicates that floors are in short supply nearby."); document.getElementById(idString).appendChild(pbreak); document.getElementById(idString).appendChild(node); } if (bFlag === 1) { node = document.createTextNode("You can hear the mailicious gossiping of giant bats coming from a nearby room."); document.getElementById(idString).appendChild(pbreak); document.getElementById(idString).appendChild(node); } node = document.createTextNode("What now ?

I have put in the various javascripts based on the product so the page is similar to a template. The syntax error is for the second set of boxes, the bracelet length options, and specifically for line with: form.amount.value = 6.5 inches; from the following script-- <SCRIPT language=javascript> function BraceletLength(form) { if (form.os0.value == "6.5 inches") { form.amount.value = 6.5 inches; form.item_number.value = "6.5 inches"; } if (form.os0.value == "7 inches") { form.amount.value = 7 inches; form.item_number.value = "7 inches"; } if (form.os0.value == "7.5 inches") { form.amount.value = 7.5 inches; form.item_number.value = "7.5 inches"; } if (form.os0.value == "8 inches") { form.amount.value = 8 inches; form.item_number.value = "8 inches"; } } </SCRIPT> I hope I have included enough information and I thank any input into this glitch I am having.

This works for every input element on the page except the <textarea>. If I move the mouse over the text area you can see the mouse blink after 2 seconds, but the help balloon does not appear unless you first give the <textarea> the focus by clicking the mouse in the area. I have verified by adding alerts that the mouseover and popup functions are called the same way on the <textarea> as on the other input elements. This is on Firefox 3.6.23 on Ubuntu 10.04.
