JavaScript - Radio Button To Enable Otherwise Locked Section
I'm having trouble programming a radio button to enable a group of checkbox options. I want the group to be disabled unless the radio is selected.
Can I use: Code: document.getElementById("").disabled=true/false for a <div> section? Here's what I have so far. function: Code: function disableSection() { if (document.forms.radio.checked) document.getElementById("optionalinfo").disabled = false; else document.getELementById("optionalinfo").disabled = true; } HTML: Code: <input type="radio" name="additionalinfo" value="yes"/>Yes! Please sign me up for the following items:<br/> <div><blockquote><input id="optionalinfo" type="checkbox" name="additional" value="newsletter"/> I wish to receive <font color="ff69b4"><i>AMT</i></font>'s monthly E-Zine, <b>"Glorious Morning Muffins"</b>.</br> <input id="optionalinfo" type="checkbox" name="additional" value="Updates"/> I wish to receive <font color="ff69b4"><i>AMT</i></font> updates.</br> <input id="optionalinfo" type="checkbox" name="additional" value="future"/> Keep me posted about future offerings at <font color="ff69b4"><i>AMT</i></font>.<br/> <input id="optionalinfo" type="checkbox" name="additional" value="userRegister"/>I need to register to log in</blockquote></div> In addition to this, I would like the section to fade when disabled.

I want to enable the radio buttons when text is entered into the field corresponding to that particular radio button. Is there a way of achieving this using a JavaScript onChange event? Thank you in advance. I am trying to make it so if a PHP session entity exists, then JavaScript will enable a button. I am having trouble getting this to work and wondering if anyone knows what I am doing wrong?

Thanks Hello, I have a script that enables a certain button when some conditions are met. I'm having an issue with it, so I made a simple script to get to the core of what I'm trying to do. This is the script that I'm using: Code: function disable() { document.form.button2.disabled='false'; } Code: <form name="form"> <input type="button" name="button1" value="Enable Button 2" onclick="disable()" /> <input type="button" name="button2" value="Button 2" disabled="true" /></form> Basically when you press button 1, button 2 enables. If I reverse it (button 2 enabled by default, pressing button 1 enables it) it is fine. But for some reason this way round nothing happens when I press button 1. What am I doing wrong? I thought this would have been fairly simple but it appears the onchange event isn't triggered when a hidden field is populated by other javascript without user input. I have a simple search box and autocomplete/suggestion ajax thingie going on. What I want to do is have my "Go" submit button disbled until AFTER a user has populated the hidden field "cid". A user populates this field automatically when they click on a suggested option from the ajax autocomplete doofer. Here's what I've tried at the moment but failed on. Code: <form action="index.php" method="GET" name="qsform" id="qsform"> <input type="hidden" name="p" id="p" value="compdetails" style="border:1px solid #000000;" /> <input type="text" name="quicksearch" id="quicksearch" value="Find Company" style="border:1px solid #000000;" onFocus="clearText(this)" onBlur="clearText(this)" /> <input type="hidden" name="cid" id="cid" value="" style="border:1px solid #000000;" /> <input type="submit" name="go" id="go" value="Go" disabled="true" onmouseover="if (document.qsform.cid.value!='') { document.qsform.go.disabled=false; }" /> </form> Hi, I am having a problem with my script used to disable my submit button. I want the button to disable upon correct submission of the form, and the button to be kept enabled if the required fields are not filled in. I have the following code at the moment (which only does the first if statement). Code: SCRIPT CODE: <script type="text/javascript" > function validateForm() { var amount=document.forms["expenserecord"]["amount"].value; var picker=document.forms["expenserecord"]["picker"].value; var desc=document.forms["expenserecord"]["description"].value; if (amount==null || amount=="" || picker==null || picker=="" || desc==null || desc=="") { alert("All required fields must be filled out."); document.getElementById("sub").disabled = false; return false; } else { document.getElementByID("sub").disabled = true; } } </script> BUTTON CODE: <p><input type="submit" value="Submit" onClick="return validateForm()" id="sub"></p> I've been handed an html document that contains a centered, scrollable <iframe> element with a static height and width. This iframe element displays a simple html document that houses the 'terms of service' text. Their goal is to have it to where the <a href> link at the bottom that is shown to the user as 'next' is disabled until the user scrolls to the bottom of the terms of agreement box. The clickable link could be a button, image or text (no preference). They have to have it this way for legal reasons and radio buttons or checkboxes will not suffice unfortunately. Question: What is the best way to go about doing this that seems to be cross-browser friendly (especially IE7). I offer $10 via paypal for well commented method/script. All: I need some help with a radio button code. It seems simple but I am really new at JavaScript so I need help. I have created a JavaScript code that has three radio buttons (High, Medium, and Low). When you click on high two text boxes appear so that an email address can be added. What I need help with is making the text boxes disappear if someone accidentally click high and then went back to low or medium. Currently the High button stays clicked and the text boxes still show. Any help would be great. Thanks, Stephen Code: <script type="text/javascript"> function showHide(el){ obj = document.getElementById(el).style; (obj.display == 'none')? obj.display = 'block' : obj.display = 'none'; } </script> <form id="form1" name="form1" method="post" action=""> <label> <input type="Checkbox" name="High" value="High" onclick="showHide('group1')" /> High </label> <label> <input type="Checkbox" name="Medium" value="Button" /> Mediun </label> <label> <input type="Checkbox" name="Medium" value="Button" /> Low </label> <p id="group1" style="display: none;"> <label> <b>friend1  </b><input type="Text" name="textGroup1" value="@gmail.com" /> <br/> </label> <br /> <label> <b>friend2  </b><input type="text" name="textGroup1" value="@gmail.com" /> </label> </p> </form> I don't exactly know how to word my issue. Basically, I need it so that if a user selects 'option1' in the group 'group1' when they go to 'group2' is only gives them a certain selection to choose from. If they choose 'option2' in 'group1' they will get a different set to choose from. My main dilemma is it must do this without them having to submit. All, I have the following code: Code: <form action="" name="myform" method="post"> <input type="hidden" id="picimages" name="picimages" value="<?php echo $resultsetstory['bigger_id']; ?>" /> <p> <label> <input type="radio" id="picimages" name="picimages" value="<?php echo $resultsetstory['picture_id']; ?>" /> <?php if($resultsetstory['title']<>""){ echo $resultsetstory['title']; }else{ echo "Image 1"; } ?> </label> <br /> <label> <input type="radio" id="picimages" name="picimages" value="<?php echo $resultsetpic2['picture_id']; ?>" /> <?php if($resultsetpic2['title']<>""){ echo $resultsetpic2['title']; }else{ echo "Image 2"; } ?> </label> <br /> <input name="submit" type="button" value="Vote!" onclick="javascript:voteupdate(this.myform);"/> </p> </form> When I submit this, it goes to this function: Code: function voteupdate(obj) { var poststr = "picimage=" + document.getElementById("picimage").value + "&bigger_id=" + encodeURI( document.getElementById("bigger_id").value ); alert(poststr); makePOSTRequest('voteresults.php', poststr); } However I can't get the value of the radio group for the one that is selected. Can someone see what is wrong? Thanks. Hi everyone. I'm getting into javascript coding and i'm stumped with some problem about radio buttons. What I would like is to have a general function where I can pass in any group of radio buttons and have it return the textual value of the radio button selected. First, here is my code so far. Code: function Get_Radio_Selection(options) { var choice = ""; for (var index = 0; index <= options.length; index++) if (options[index].checked == true) choice = options[index].value; return choice; } Now here's a sample form: Code: <form name="form1"> <input type="radio" name="food" value="Banana">Banana <input type="radio" name="food" value="Mango">Mango <input type="radio" name="food" value="Orange">Orange <input type="radio" name="food" value="Oatmeal">Oatmeal <input type="button" name="blah" value="Get Selection" onclick="Get_Radio_Selection(document.form1.food);"> </form> My question is, when i run this function and pass it in the group of radio buttons by means of the onclick event handler, firefox 3.6.22 reports in the error console on line 22 that "options[index] is undefined". It seems that if i use the variable "index" more than one time it reports this error but if I take out the assignment to variable "choice" that it works just fine. I rewrote the function using a separate variable and this time it works perfectly: Code: function Get_Radio_Selection(options) { var choice = ""; var index; for (var i = 0; i < options.length; i++) { if (options[i].checked == true) { index = i; choice = options[index].value; } } return choice; } Notice the indexing variables in the "if" statement and the assignment to "choice" are different. Does anyone have any suggestions on why this happens? Thanks. I'm trying to make radiobuttons with a javascript function that gets called when a button is selected to make an image appear depending on what they click. However, after looking it up for a while I have nothing since some tell me to do document.formName.name.value; some tell me to use an id with my buttons and just use a document.getElementByID(""); etc. This is for a project and we havent used parameters yet and I dont know how to implement them in the HTML as well This is my code: function classchoice() { if(document.getElementById('mage') == true) { classtype = "<img class='display' src='mage.jpg'>"; document.getElementById("picture").innerHTML=classtype; } if(document.classes.classes.paladin == true) { classtype = "<img class='display' src='paladin.jpg'>"; document.getElementById("picture").innerHTML=classtype; } if(document.classes.classes.hunter == true) { classtype = "<img class='display' src='hunter.jpg'>"; document.getElementById("picture").innerHTML=classtype; } if(document.classes.classes.rogue == true) { classtype = "<img class='display' src='rogue.jpg'>"; document.getElementById("picture").innerHTML=classtype; } } This is the HTML: <form name="classes"> <input type="radio" name = "classes" id="mage" onmousedown="classChoice();"> <img src = "mage.jpg" /> <input type="radio" name = "classes" id = "Paladin" onmousedown="classChoice();"> <img src = "Paladin.png" /> <input type="radio" name = "classes" id = "hunter" onmousedown="classChoice();"> <img src = "hunter.PNG" /> <input type="radio" name = "classes" id = "rogue" onmousedown="classChoice();"> <img src = "rogue.jpg" /> </form> I hope it's readable because I copy and pasted my code and the indentations are a bit messed up Hi, I am trying to use the radio button to display the information for the users. For example, when I click radio button "1", the form should display 1 text box each for first name, last name and so on. When the user clicks on radio button 2, there should be text boxes displayed for user 1 and user 2 to enter their info(first name, last name and so on). I looked at the forum, but couldn't find something similiar.Please advise. Something like ================================ Number of Users 1 2 3 # if radio button 2 is selected then User 1 First Name Last Name User 2 First Name Last Name ================================ The code is as below: <html> <head> <script type="text/javascript"> function showUser() { for(i=0;i<document.form.users.length;i++) { if (document.form.users[i].checked) val=parseInt(document.form.users[i].value); for(j=0;j<=val;j++) { document.form.write("<table cellSpacing=1 cellPadding=0 width=600 border=0>"); document.form.write("<tr> <td width='20%' align='right'><font color="#660000"><b>First Name: </b></font></td>"); document.form.write("<td><input type='text' name='fname1' size='25' maxlength='25'></td></tr>"); document.form.write("<tr><td width='20%' align='right'><font color="#660000"><b>Last Name: </b></font></td>"); document.form.write("<td><input type='text' name='lname1' size='25'maxlength='25'></td></tr>"); document.form.write("</table>"); } } } </script> </head> <form> Check the number of users to display additional input fields.<br><br> <input type="radio" name="users" value="1" onclick = "showUser()"/> 1<br/> <input type="radio" name="users" value="2" onclick = "showUser()"/>2 <br/> <input type="radio" name="users" value="3" onclick = "showUser()"/>3 <br/> </form> </html> ======================================================== Thanks in advance. Hello Friends, i have a small problem and need your help.
