JavaScript - Radio Button Values
Hello I am very new to Java Script. I am working on a website which requires me to use it. The site is selling items that are priced depending on the size. There are 6 fixed sizes for the width and the length can come in any size 1 through 200. So that will be user input on the length and radio buttons on the width. I am trying to have the user put in the length and click a radio button for width and then calculate the price by multiplying them. I am trying to get 1 price to display right now just to test it but I can't figure out why it isn't working. Again I am fairly new at this so there might be multiple problems with my code. Thanks in advance for the help.
Code: <script type = "text/javascript"> function buttoncheck(){ var selection1 = document.menu.selection; if (selection1 == 60) {choice1()} if (selection1 == 50) {choice2()} if (selection1 == 25) {choice3()} if (selection1 == 10) {choice4()} if (selection1 == 4) {choice5()} if (selection1 == 2) {choice6()} function choice1(){ var len = Number(document.getElementById("length").value) || 0; var area1 = selection1 * len; var cost = 0; if (area1 == 60) { cost = 60} return cost; document.getElementById("TotalCost").innerHTML = "$" + cost.toFixed(2); } Code: <h4 class="auto-style3">Pricing Calculator:</h4> <p> <form method="post"> <div class="auto-style1"> <span class="auto-style2">LENGTH:</span> <input name="length" type="text" id="length" /><br /> </form> <div class="auto-style1"> <form name="menu"> <input type="radio" value="60" name="selection">60 inch</input> <input type="radio" value="50" name="selection">50 inch</input> <input type="radio" value="25" name="selection">25 inch</input> <input type="radio" value="10" name="selection">10 inch</input> <input type="radio" value="4" name="selection">4 inch label</input> <input type="radio" value="2" name="selection">2 inch label</input> </form> </div> <p class="auto-style1"> <input type="button" value="Calculate" onClick="buttoncheck()" </p> </p> <p> </p> <span id="TotalCost"></span><script type = "text/javascript"> document.getElementById("TotalCost").innerHTML = "Total cost is $" + cost.toFixed(2); Similar TutorialsI have 4 rows in a table. Each row consist of 4 radio buttons. Each radio button per row has different values in it but has the same name (group) ex: <input type="radio" name="a" value="1"> <input type="radio" name="a" value="2"> <input type="radio" name="a" value="3"> <input type="radio" name="a" value="4"> <input type="radio" name="b" value="1"> <input type="radio" name="b" value="2"> <input type="radio" name="b" value="3"> <input type="radio" name="b" value="4"> and so on.. If I click radio button A with value 2, I want to output the total at the bottom as "2".. Also, if I click radio button B with value 3, I want to output the total of A and B as 5 and so on.. How can I automatically calculate the answer based on which radio button was click? update: I got my answer from this site: http://stackoverflow.com/questions/1...s-using-jquery I have some asp:radiobutton lists that need to update a label with the sum of their values each time a user selects a new value. I am brand new to javascripting and would like some insight on how to get this done. I have inserted my code below. Code: <asp:Label runat="server" Text="Greeting:" /> <asp:Label runat="server" ForeColor="Red" ID="lbl_GreetingScore" Text="0" /> <asp:RadioButtonList ID="rdb1_1" runat="server" RepeatDirection="Horizontal"> <asp:ListItem Selected="True" Text="N/A" Value="4" /> <asp:ListItem Text="Yes" Value="4" /> <asp:ListItem Text="No" Value="0" /> </asp:RadioButtonList> Hey javascript newbie, Im trying to figure out how to add different radio if its selected or not example: Radio_Button1 value="5": Selected Radio_Button2 value="15": Not Selected Radio_Button3 value="25": Selected Radio_Button4 value="35": Selected var addingitup = ??? and im lost???? I am using ASP validators and I have a contact form. I want to be able to have a phone and email radio button group. The email textbox also has a RegularExpressionValidator If the phone item is selected then I want the validation to be enabled on the phone text box making it mandatory while the email text box isn't, and if they choose the email as the contact it will be reversed. I want to be able to do this without having to do a postback. I already have the logic on the code behind and the enquiry object. also I am fairly new to javascript so I have been using mostly jQuery as easier to implement I have a page where a user can select (via check boxes) several categories. Each category is related to a set of possible options (radio buttons) that have numeric values. When one of the options (radio button) is selected, the amount will appear in a text box (input type="text"). The numeric value in the text box will update depending on what category options are selected. However, when the checkbox is deselected, the radio boxes in the <div> are not displayed and I need to remove (reset) the radio button values from the value seen in the text box. Here are some snippets to hopefully expound on what I would like to do. Code: <script type="text/javascript"> var amountNotice = 0; function notice(options) { amountNotice = parseInt(options); calculateTotal(); } function calculateTotal() { totalAmount = amountNotice; document.getElementById("total").value = totalAmount.toFixed(2); } function toggle(chkbox, group, associatedValues) { var visSetting; if (chkbox.checked == true) document.getElementById(group).style.display = "inline"; else { document.getElementById(group).style.display = "none"; uncheckRadio(associatedValues); } document.getElementById(group).style.display = visSetting; } function uncheckRadio(associatedValues) { for(var i = 0; i < document.getElementById(associatedValues).length; i++) { if (associatedValues[i].checked == true) associatedValues[i].checked == false; } calculateTotal(); } </script> <style type="text/css"> #groupNotice {display: none} </script> . . <input type="button" onClick="calculateTotal()" value="Calculate"><br> <div id="groupNotice"> <b>Required Notice</b>: <input type="radio" name="Note" onClick="notice(this.value)" value="0"> None <input type="radio" name="Note" onClick="notice(this.value)" value="2"> Prior Day ($2) <input type="radio" name="Note" onClick="notice(this.value)" value="2"> Prior Call ($2)<br> </div> <form name="CostEstimate" method="post" action="calculator.php"> <input type="checkbox" onclick="toggle(this, 'groupNotice', 'Note'); display('groupNotice','inline')" name="Notice" value=""> Notice </form> Everything works except for my uncheckRadio function - not sure if I am identifying the elements correctly, or if I need a totally new approach. My thinking is that the function must be accessed by the checkbox onClick call. Previously I had tried calling uncheckRadio from the notice function before I recognized is was not an appropriate location. Any assistance is greatly appreciated. - c I keep getting 28 when I am suppose to get 22 because of Order of Operations.

Can someone see what is wrong? Thanks. 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 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 have this frameset: http://www.mediafire.com/?75dvswgvelw19a9 this is somehow the like my other posts but im dealing with the radio buttons. what i want is when i click on the "create" button in form1 http://www.mediafire.com/?eld7a1rb21h799e it will pass the value to form 2 http://www.mediafire.com/?f0o060cdpyf06ya. so when i select "yes" in form1 and click on "create" it will autoselect "On" in form2. if i select "no" in form1 and click on "create" it will autoselect "off" in form2. How can I style the background of a radio button? I have a form where it validates the users has selected one of the radio group values. If they don't the group gets focus and I would like to highlight the radio group. I tried the below it it seems focus goes to the correct group but no background changes. Now I know you can change the background of radios and apply a border of you would like. What am I doing wrong woth this. Code: <script type="text/javascript"> function validate(){ document.forms[0].myradio[0].checked = true document.forms[0].myradio[0].style.border='2px dotted #00f'; document.forms[0].myradio[0].style.backgroundColor='#ffff99'; } </script> <form name="test" name="theForm" onsubmit="validate()"> <input type="radio" name="myradio" /> <input type="radio" name="myradio" /> <input type="radio" name="myradio" /> <BR> <BR> <BR> <BR> <input type="radio" name="myradio2" /> <input type="radio" name="myradio2" /> <input type="radio" name="myradio2" /> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <input type="radio" name="myradio3" /> <input type="radio" name="myradio3" /> <input type="radio" name="myradio3" /> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <input type="radio" name="myradio4" /> <input type="radio" name="myradio4" /> <input type="radio" name="myradio4" /> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <input type="radio" name="myradio5" /> <input type="radio" name="myradio5" /> <input type="radio" name="myradio5" /> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <input type="radio" name="myradio6" /> <input type="radio" name="myradio6" /> <input type="radio" name="myradio6" /> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <input type="submit" value="submit" name="submit"> </form> I have the following code which I want to make a selection and the value should reflect in the text box and the text box should take on that value for future calculations.

This last part is what I would like to prevent. Say a user selects the option 'car' and then for some reason clicks on the same option again, this will lead to the OnProductClick function being executed twice. How can I prevent the second execution? I am ignorant in java scripting. I want to use the following java script to create the radiobutton in obiee reporting. This java script will change the regular prompt to radio button,however I do not know how to debug if it is working. Waiting for kind reply.

I'm trying to get the value of a radio button when clicked. I'm dynamically creating these radio buttons while populating a table like this: Code: var rad for(blah blah blah){ insert array data into table... insert array data into table... insert array data into table... rad = document.createElement('input'); rad.setAttribute('type', 'radio'); rad.setAttribute('name', 'options'); rad.setAttribute('value', id); rad.onclick = function() { doSomething() }; cell.appendChild(rad); } If I'm in the doSomething function, how do I access the value or ID of the radio button? Thanks! |
