JavaScript - Getting An Element Inside Of An Innerhtml
Hi guys,
I have a <div> tag that is getting updated by calling a php script. Inside of the div's innerHTML, there is a <select> tag. I need to be able to change the div whenever a user changes the select tag. How can I do this? I've been trying to get the select tag, but it doesn't seem to evaluate right. Ex: (note, the select's name is "courseselect") Code: var thediv = document.getElementById("mydiv"); var selectMenu = thediv.getElementsByTagName("select"); var selector; for (var i = 0; i < selectMenu.length; i++) { var currAtt = selectMenu[i].getAttribute("name"); if (currAtt == "selectcourse") { selector = selectMenu[i]; } } selector.onChange = function() { alert("something has changed!"); } Any help is appreciated. Thanks! Similar TutorialsHi, 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! I have the non-standard element Code: <testele></testele> In every browser except IE, this bit of JavaScript will successfully change the content of the above element Code: document.getElementsByTagName("testele")[0].innerHTML = 'hi'; However, if I change the <testele> to just a <span> (in the HTML and the JavaScript), it now successfully changes the content of the element in every browser, including IE. Is there any fix? I have searched around and tried a bunch to no avail. Thanks! Hey all! Got a question I can't seem to find an answer to. I have a little JS app that is a glorified calculator which I posted the code for below. My code uses the document object to replace the html in the "content" <div> and works great. However, I want to add an inline style in order to change the background of the input (readonly field with an id of "coutput") based on either of the global variables named "MJPD" or "IJPD", (depending on the switch case selected in the user prompt at the beginning of the script.) Simplified....if the value of MJPD is less than 4.6, I want the "coutput" field's background to be red, else be green. The same goes for IJPD, except the threshold for red will be <3.83. Code and what I have tried is below. After reading the code, look below it to see what I have tried and maybe tell me what I'm doing wrong! =) Any help is greatly appreciated.......I have spent a week searching for this little answer and I can't seem to find it! Code: <script language="JavaScript"> var MJPD = 1; var IJPD = 1; function sayhello(){ // *** live test for inline JS code placement alert("IT WORKS!!! Now change me =)"); } ////////////////////////////////////////////////////// function changeScreenSize(w,h) { window.resizeTo( w,h ) } /////////////////////////////////////////////////// function iJPDCalc(form) //calculate IJPD value { var ij = parseFloat(form.IJobs.value, 10); var it = parseFloat(form.ITime.value, 10); var IJPD = 0; IJPD = (ij / it) * 8.0; form.I_JPD.value = IJPD; } ///////////////////////////////////////////////////// function mJPDCalc(form) //calculate MJPD value { var mj = parseFloat(form.MJobs.value, 10); var mt = parseFloat(form.MTime.value, 10); var MJPD = 0; MJPD = (mj / mt) * 8.0; form.M_JPD.value = MJPD; } ///////////////////////////////////////////////////// function ijpdcolor() //set bg color of coutput based on IJPD's value { if (IJPD >= 3.83) { return ("green"); } else { return ("red"); } } ///////////////////////////////////////////////////// function mjpdcolor() //set bg color of coutput based on MJPD's value { if (MJPD >= 4.6) { return ("green"); } else { return ("red"); } } ///////////////////////////////////////////////////// function startVZT3(){ var n=0; n=prompt("What would you like to do? 1: Calculate IJPD 2: Calculate MJPD 3: Exit", "Enter a value from 1-3") switch(n) { case(n="1"): document.getElementById("content").innerHTML='<FORM><h2>Combined IJPD Calculator</h2><p>Install components completed today:</p><INPUT NAME="IJobs" VALUE="3.84" MAXLENGTH="10" SIZE=10><p>Hours taken to the jobs:</p><INPUT NAME="ITime" VALUE="8" MAXLENGTH="10" SIZE=10><h4> Click the button to calculate your IJPD:</h4><INPUT NAME="calc" VALUE="Calculate" TYPE=BUTTON class="cbutton" onClick=iJPDCalc(this.form)><p>Your current combined IJPD for today is:</p> <INPUT NAME="I_JPD" class="output" style=" " id="coutput" READONLY SIZE=10></FORM>'; break case(n="2"): document.getElementById("content").innerHTML='<FORM><h2>Combined MJPD Calculator</h2><p>Trouble components completed today:</p><INPUT NAME="MJobs" VALUE="4.6" MAXLENGTH="10" SIZE=10><p>Hours taken to the jobs:</p><INPUT NAME="MTime" VALUE="8" MAXLENGTH="10" SIZE=10><h4> Click the button to calculate your MJPD:</h4><INPUT NAME="calc" VALUE="Calculate" TYPE=BUTTON class="cbutton" onClick=mJPDCalc(this.form); mjpdcolor();><p>Your current combined MJPD for today is:</p> <INPUT NAME="M_JPD" class="output" style=" " id="coutput" READONLY SIZE=10></FORM>'; break case(n="3"): alert('This page will now close...'); window.close(); break default: document.getElementById("content").innerHTML='<h1 style="padding-top: 40px; color: red;">You need to enter a value!

Theoretically, this should pull the value of MJPD (or IJPD), evaluate it for the if statement, then return the value of red or green and set the value of the background dynamically - but of course it doesnt. I have also tried different inline styles and even adding the css id and trying to link it to the mjpdcolor() function, but all to no avail. Can someone help me please?? Thanks everyone, your awesome! Hi I have this page below which I run locally that is created dynamically: I need a piece of javascript to focus on the captcha as shown in the image inside the green box. At this minute I have this which doesn't work all that great for some reason but it gets it to the general area... Code: if (( document.URL.indexOf("cast_skills") != -1 ) || ( document.URL.indexOf("security_prompt") != -1 ) || ( document.URL.indexOf("joinraid") != -1 )){ if ( document.forms.length > 0 ) { document.forms[0].elements[1].focus(); } } As I said this does the job to some extent however it does not leave the focus in a perfect position so that the captcha is readable and the text box visible to type in, as illustrated in the red box in the above image. Help with this would be great. Many thanks, David. Here's my object constuctor: Code: function suggest_object(result_id) { this.in_result_div = false; this.search_element = document.getElementById(result_id); } And the execution code: Code: var suggest = new suggest_object(result_id); document.getElementById(result_id).onmouseover = function(){suggest.in_result_div = true;} It works as is, but i'd really like to be able to set the onmouseover inside of the object. Something like Code: function suggest_object(result_id) { this.in_result_div = false; this.search_element = document.getElementById(result_id); this.input_element.onmouseover = function() { this.in_result_div = true; } } So how can I get the 'this' inside the onmouseover function to refer to the object?

Hey, for some reason, this isn't working because of the src="images/edit.png" attribute. Here is my code: Code: <a href="#" onclick="change('HEYYY')"><img src="images/edit.png" alt="Edit" id="edit1" /></a> Javascript (External) Code: function change(message) { document.getElementById('edit1').innerHTML = '<input type="text" value="'+message+'" />'; } It does nothing. But if I take the src attribute out, it works fine. Any help? Thanks. Does anyone have any suggestions as to how I can get IE working properly with this? It's a, (exempting IE), straight forward line numbering and plain text code view function. When using the line numbering portion, it works fine in Moz based browsers etc, as it does in IE for the initial numbering. On trying to remove the numbers though, (on the second call), IE just seems to cascade the list entries rather than removing them. Code: function process_code(id, number, print) { if (document.getElementById(id)) { var current = document.getElementById(id); var code = current.innerHTML.split('\n'); var count = 0; var xcount = 0; if (number) { if (current.innerHTML.indexOf('<li class="code-entry">') != -1) { code = code.join('\n'); code = code.replace(/\<\/(li\>\<\/ol|li)\>/ig, '\n'); code = code.replace(/\<ol\>\<li[^\>]+\>|\<li[^\>]+\>/ig, ''); current.innerHTML = code.replace(/^\n+|\n+$/g, ''); } else { current.innerHTML = '<ol><li class="code-entry">'+code.join('</li><li class="code-entry">')+'< /li></ol>'; } } else { var doc = window.open('', 'code_print'); var newdoc = doc.document; newdoc.open('text/plain'); newdoc.write(decode_code(code.join('\n'))); newdoc.close(); if (print) { if (navigator.userAgent.indexOf('Opera') != -1) { window.print(); } else { doc.print(); } doc.close(); } } } } How would you make a if for a input box =this do this Some if the input boxe value = this then get innerHTMl Hello, I am a newbie for Javascript. Currently I am doing a website which consists of a lot of contents. Therefore, I hope to get a solution which all my contents are arranged into a table (rows and columns). The condition is that there is only a html page to hold all the contents where there is a "view more" or 'next" button at the bottom and each times user can click to go to the different contents. I have tried to use the innerHTML and I was able to do for 2 pages only...Now I encountered a problem which I need to update more contents to more pages .

I've created a test page with loads of comments on the source, as this is quite hard to explain. phurley.co.uk/test.php - (if you select 'specific date', this is the one i'm trying to get working for now) Basically, I have a text box that when selected makes a calendar pop up. This works fine, but I am now making the html for the text box be produced via innerHTML in a JS function (with select boxes and a case/break), and the pop up no longer works. I've tried all night to get this working but my JS skills are letting me down.
