Thanks, Cs1h I was trying to get total amount from these all checkbox, when I submit, but I don't know somewhere wrong. Please help me out. Here is my code: <html xmlns = "http://www.w3.org/1999/xhtml"> <head> <title> Form </title> <script language = "JavaScript"> // The event handler functions for the check boxes function appleHandler() { var number = document.orderForm.apples.value; total = total + number * 0.59; } function orangeHandler() { var number = document.orderForm.oranges.value; total = total + number * 0.49; } function bananaHandler() { var number = document.orderForm.bananas.value; total = total + number * 0.39; } // The event handler function to produce the total cost message // when "submit" is clicked function finish() { total = total * 1.05; alert("Thank you for your order \n" + "Your total cost is: $" + total + "\n"); } </script> </head> <body> <h3> Order Form </h3> <form name = "orderForm" onSubmit = "finish()"> <p> <input type = "checkbox" name = "apples" size = "3" onClick = "appleHandler()" /> Apples </p><p> <input type = "checkbox" name = "oranges" size = "3" onClick = "orangeHandler()" /> Oranges </p><p> <input type = "checkbox" name = "bananas" size = "3" onClick = "bananaHandler()" /> Bananas </p><p> <input type = "reset" name = "reset" /> <input type = "submit" name = "submit" /> </p> </form> </body> </html> I am making a google CSE for a client site and I need to concatenate checkbox values together on the end of another form value. So I have a text box and the checkboxes: Code: <input name="q" cid="q" size="25" maxlength="50" value"off road tires"> <input type="checkbox" name="q" id="q" value="cooper|hankook" /> <input type="checkbox" name="q" id="q" value="Mickey Thompson|Bfgoodrich|GBC" /> <input type="checkbox" name="q" id="q" value="Hoosier|Nitto" /> For Google the URL string needs to be like this: Code: results.html?q=off road tires AND inurl:cooper|hankook|Mickey Thompson|Bfgoodrich|GBC this string says the person did not check the last box. I am having a hard time trying to do this. If you guys know a better way to accomplish the same thing I am all ears but I thought I would bring it to the experts and see what they had to say. Thanks for the help! Looking for a simple method to Toggle textbox yes/no using CheckBox This example does not work! But I hope this will help explain what I am trying to do Code: <SCRIPT LANGUAGE="JavaScript"> function YesOrNo() { if(document.formname.checkboxname.checked) { document.formname.textname.disabled='Yes'; } else { document.formname.textname.disabled='No'; }} </SCRIPT> <form name="formname"> <input type="text" size="10" name="textname"> <input type="checkbox" onclick="YesOrNo()" name="checkboxname" value="Yes"> </form> Firebug returns an error saying msg.elements is undefined.

Close thread please. New problem in post below VVV Hi all, Can anyone point me in the right direction for some sample code that when the selection on a checkbox changes, either writes or removes some content? In this instance, when the checkbox is unchecked, I want more table rows and columns written with the relevant data within them. Then when checked, I want this data removed. Many thanks Hi everyone; I have created a JavaScript function to show either a enabled or a disabled text input field depending on whether a checkbox has been clicked or not. It works great for that purpose. However, when I use it for more than one text input field and I submit the form, it goes back to its disabled form. This is a problem if you by mistake submit the form without filling all the fields. As I said, the submit button makes the form go disabled. Is there a way to either not have the form go disabled after submission or to have a "Oncheck" function so I can use $_SESSION to keep the checked attribute? Thanks in advance for all your help Code: <html> <head> <style type="text/css"> #Active { display:none; } </style> <script type="text/javascript"> function toggle() { if (document.getElementById) { if (document.getElementById("checkbox").checked == true) { document.getElementById("Active").style.display = "block"; document.getElementById("Inactive").style.display = "none"; } else { document.getElementById("Inactive").style.display = "block"; document.getElementById("Active").style.display = "none"; } } } </script> </head> <body> <?php echo "Add Field"; echo "<input type=\"checkbox\" name=\"check\" id=\"checkbox\" onClick=\"toggle();\" value=\"v\"/>"; echo "<form method=\"post\">"; echo "<div id=Active>"; if(isset($_SESSION['test']) && $_SESSION['test']!="") { echo "<input name=\"test\" value=\"". $_SESSION['test']."\" type=\"text\" />"; } elseif(isset($_POST['test']) && $_POST['test']!="") { echo "<input name=\"test\" value=\"". $_POST['test']."\" type=\"text\"/>"; } else { echo "<input name=\"test\" type=\"text\"/>"; } echo "<input type=\"text\" name=\"test2\" >"; echo "</div>"; echo "<div id=Inactive>"; echo "<input type=\"text\" disabled>"; echo "<input type=\"text\" disabled>"; echo "</div>"; echo "<input type=\"submit\">"; echo "</form>"; $test = $_POST['test']; $_SESSION = $_POST['test']; $test2 = $_POST['test2']; $_SESSION = $_POST['test2']; echo $test; ?> </body> </html> All, I have the following checkbox code: PHP Code: echo "<input name=\"picbigid[]\" type=\"checkbox\" value=\"$pic[src_big]\">"; I then want to select all the checkboxes so I have this code: [PHP] echo "<input type=\"button\" name=\"CheckAll\" value=\"Check All\" onClick=\"checkAll(document.photos.picbigid)\"> <input type=\"button\" name=\"UnCheckAll\" value=\"Uncheck All\" onClick=\"uncheckAll(document.photos.picbigid)\">"; [PHP] My JS function is: Code: function checkAll(field) { for (i = 0; i < field.length; i++) field[i].checked = true ; } function uncheckAll(field) { for (i = 0; i < field.length; i++) field[i].checked = false ; } If I do it like this: PHP Code: echo "<input name=\"picbigid\" type=\"checkbox\" value=\"$pic[src_big]\">"; It works but I can't have it like that because the form posts to another PHP page that needs the input name as an array. Any ideas? Thanks! hi i was wondering if there was anyway i can check a check box with the help of javascript and have it add text from a database record to a text box without submitting the page with the help from php? i have the php coding done to get the info and edit it but cant have no idea how to do the javascript code thanks.

Then I am using JavaScript to validate that the user has selected at lest 1 of the given box's before I do a post back. But I cannot get my Javascript to see my CheckBox Array. Any help you can offer would be very useful thank you all in advance. Here is my PHP code used to build to Checkbox list. Code: while ($row = mysql_fetch_array($data, MYSQL_ASSOC)) { if(is_null($row['Team_Number'])) { $str1 = sprintf('<input type="checkbox" name=\'People\' value="%s">',$row['Member_ID']); } else if($row['Team_Number'] == $_REQUEST['T']) { str1 = sprintf('<input type="checkbox" name=\'People\' value="%s" checked>',$row['Member_ID']); } else { $str1 = sprintf('<input type="checkbox" name=\'People\' value="%s">',$row['Member_ID']); } $str = sprintf('%s,%s (%s)',$row['First'],$row['Last'],$row['Nick_Name']); echo('<tr><td width ="10%" align="center">'); echo($str1); echo('</td><td width="90%" align="Left">'); echo($str); echo('</td >'); echo('</tr></td>'); } And here is my Javascript, I've added the whole function incase it's not clear just from a code segment. Code: function TeamSetup() { var required = document.form1.BowlersPerTeam.value; var total = document.form1.People.length; var Tm = document.form1.TeamName.value; var cnt = 0; var peopleIDs = ""; var test = document.getElementsByName('People'); if(isArray(document.form1.People)) { for(var i=0; i < total; i++) { if(document.form1.People[i].checked) { if(peopleIDs.length > 0) { peopleIDs = peopleIDs +","; } peopleIDs = peopleIDs + document.form1.People[i].value.toString(); cnt++; } } } else { if(document.form1.People.checked) { cnt=1; peopleIDs = peopleIDs + document.form1.People.value.toString(); } } if(Tm.length > 0) { if(cnt == required || cnt > 0) { //Hand off to next step for completeing Processing. var myForm = document.createElement("form"); myForm.action=window.location; myForm.method="Post"; myForm.appendChild(createformInput("Process","PP")); myForm.appendChild(createformInput("people",peopleIDs)); myForm.appendChild(createformInput("Team",GetQueryString("T"))); myForm.appendChild(createformInput("League",GetQueryString("L"))); myForm.appendChild(createformInput("TeamName",Tm)); document.body.appendChild(myForm); myForm.submit(); } else { alert('You need to Select at least 1 player'); } } else { alert('You need to enter the team name!'); } } Hello all, I usually try and solve my problems by reading all post but i i'm having problem trying to find a solution my problem.

Regards Hey guys, I am having a bit of an issue here. I have a form which has 3 checkboxes in it: (sorry, ignore the asp) Code: <input name="certs" id="certs" type="checkbox" <% If certs="on" Then Response.Write("checked=""checked""") %> /> <input name="nocerts" id="nocerts" type="checkbox" <% If nocerts="on" Then Response.Write("checked=""checked""") %> /> <input name="certsna" id="certsna" type="checkbox" <% If certsna="on" Then Response.Write("checked=""checked""") %> /> Anyways, I want to enforce the following: - Only one checkbox can be checked from these 3, no more - At least one checkbox must be checked before submission I have found a couple small scripts to validate that at least one is pressed, but I do not know how to make sure no more than one is pressed, and how to combine scripts is beyond me. Can anyone offer any assistance? Is this difficult to do? Hi. I have a list of checkboxes with Ids that go something like; chk_AGE=16 chk_AGE=17 chk_AGE=18 chk_GENDER=MALE chk_GENDER=FEMALE chk_RANK=OFFICER chk_RANKE=OTHER When a user checks/unchecks '16' (for example), I want javascript to look up how many checkboxes in my form have an Id that begins with "chk_AGE" and return the number in an alert box ("3" in this case). If my user had checked/unchecked "Officer" an alert box would return "2" as there are 2 checkboxes that begin "chk_RANK". Can someone please help with this? I am a complete javascript beginner. |
