So I want to hide a radio button until my form is filled out but I don't know how. I tried .hide(); and that worked when I put it outside of my .submit function but doesn't work inside of it. This is using jquery and bootstrap.
Here is a small version of the JS I have ('agree' is the radio button):
$('myForm').submit(function(e){
var firstName = $('first-name').val();
var pattern = /^$/;
var error = '';
var checkbox = document.getElementById('agree');
if(pattern.test(firstName)){
error += 'Error: enter first name.\n';
}
if(error.length != 0){
alert(error);
e.preventDefault();
}
});
I want to hide the radio button until the first name part of the form is filled out then the radio button will appear.
Put an id in your radio like this :
<input type="radio" id="rad" />
Then hide it like this using jquery :
$('#rad').hide();
Then an example of how you can make it show when something happens would go a bit like this :
If ($('#something') > 10) {
$('#rad').show();
}
Hope this helped :)
I would use plain JavaScript for this:
<input type="text" name="first-name" value="" onchange="document.getElementById('agree').style.display = (this.value == '' ? 'block' : 'none' );"/>
<input type="checkbox" name="agree" value="Agree" style="display:none"/>
Edit:
Other ways to do this is to use onkeydown, onkeyup or onblur instead of onchange
Here is a simple example using jquery... http://jsfiddle.net/wa8rxj43/2/
HTML
<input type="text" id="name" class="name">
<input class="not-display" id="somecheck" type="checkbox" name="vehicle" value="Car" checked>
JavaScript
$('#somecheck').hide();
$("#name").bind({
'input':function(){
if(this.value.length > 0)
{
$('#somecheck').show();
}
else
{
$('#somecheck').hide();
}
}
});
Edit: Removed CSS per OP's request.

I'm trying to enable/disable a place order button based on whether or not the terms acceptance checkbox has been checked. The script I have been working on works fine for that, but it's also triggered when a different checkbox (with a different id) is checked. Although the other checkbox enables the button, it doesn't disable it again when un-checking it. So I think it's something wrong with the 'on change' part.
I've tried everything I could find and can't make it work only when the checkbox with id 'terms' is checked:
<script>
jQuery(window).on('load',function(){
setTimeout(function(){
jQuery('#payment #place_order').attr("disabled","disabled");
},1000);
});
jQuery(document).on('change','#terms',function() {
var ischecked = document.getElementById("terms");
if(ischecked.checked == false){
jQuery('#payment #place_order').attr("disabled","disabled");
}else{
jQuery('#payment #place_order').removeAttr("disabled");
}
});
</script>
The terms checkbox is as below:
<input type="checkbox" class="woocommerce-form__input woocommerce-form__input-checkbox input-checkbox ios-switch" name="terms" id="terms">
And the other one that triggers it is as below:
<input class="woocommerce-form__input woocommerce-form__input-checkbox input-checkbox" id="createaccount" type="checkbox" name="createaccount" value="1">
Your code is not clear.
Assuming the place order has the id of #place_order, there is no need to add the container
jQuery(function() { // on page load
jQuery('#place_order').attr("disabled", "disabled");
jQuery(document).on("change", "#terms", function() { // assuming the terms is dynamically inserted
if (!this.checked) {
jQuery('#place_order').attr("disabled", "disabled");
} else {
jQuery('#place_order').removeAttr("disabled");
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
Terms <input type="checkbox" class="woocommerce-form__input woocommerce-form__input-checkbox input-checkbox ios-switch" name="terms" id="terms"><br/>
<button id="place_order">Place order</button>
<hr/>
Create account <input class="woocommerce-form__input woocommerce-form__input-checkbox input-checkbox" id="createaccount" type="checkbox" name="createaccount" value="1">
i'm basically JavaScript newbie and I'm trying to resolve this problem of mine for quite a while. So,i'm doing JS school project and I need to make connection between checkbox and text form. If checkbox is not checked, text form should be disabled and vice versa. This is piece of code I have written:
function cbtf() {
if (document.getElementById('checkbox').checked==false) {
document.getElementById('textform').disabled=true;
}
}
Can anyone write a new code ? That would be much of a help.
Simply attach a method to checkbox's onclick handler:
function enableElement(id, enable) {
document.getElementById(id).disabled=!enable;
}
<label>
<input
type="checkbox"
onclick="enableElement('textform', this.checked)"
/>
ENABLE
</label>
<br/>
<textarea id="textform" style="width:100%; height:200px" disabled>
THIS IS TEXTAREA WITH ID "textform"
</textarea>
or another simplification without creating special one-liner method - just define Your will directy in onclick event:
<label>
<input
type="checkbox"
onclick="document.getElementById('textform').disabled = !this.checked"
/>
ENABLE
</label>
<br/>
<textarea id="textform" style="width:100%; height:200px" disabled>
THIS IS TEXTAREA WITH ID "textform"
</textarea>
You can add a click event to the checkbox, and assign it's check state to the disabled property of the TextBox.
document.querySelector('input[type=checkbox]').onclick = function(e) {
document.querySelector('input[type=text]').disabled = e.target.checked;
};
<input type="checkbox" name="">
<input type="text" name="">
You won't get that to work unless you attach an event to the checkbox, so I would suggest something like this:
var textbox = document.getElementById('textform');
var checkbox = document.getElementById('checkbox');
checkbox.addEventListener("change", function() {
if (checkbox.checked) {
textbox.disabled = false;
} else {
textbox.disabled = true;
}
})
I have a variable that contains a radio button value. I check some conditions, and based on this value the radio button will be selected.
if(cheque_date == system_date) {
cheque_value='Current';
}
else {
cheque_value='PDC';
}
cheque_value = $('input[name=cheque_type]:checked').val();
Radio button:
<label class="radio">
<input type="radio" name="cheque_type" value="Current" />Current
</label>
<label class="radio">
<input type="radio" name="cheque_type" value="PDC" />PDC
</label>
Is this right?
You can check radio button based on value like following.
if(cheque_date == system_date) {
cheque_value='Current';
}
else {
cheque_value='PDC';
}
$('input[name=cheque_type][value="'+cheque_value+'"]').prop('checked', true);
You need some modifications in your code:
1) Add ids to your checkboxes. In HTML, id attribute is unique, so selecting elements with id is much more faster than by classes or tags.
2) Get id in a variable and use that runtime variable in jQuery.
Final code:
<label class="radio">
<input type="radio" name="cheque_type" value="Current" value="Current"/>Current</label>
<label class="radio">
<input type="radio" name="cheque_type" value="PDC" value="PDC" />PDC</label>
AND jQuery code:
var cheque_id = (cheque_date == system_date) ? 'Current' : 'PDC';
cheque_value = $('#'+cheque_type+':checked').val();
Can you try the code below ?
if(cheque_date == system_date)
cheque_value = 'Current';
} else {
cheque_value = 'PDC';
}
$("input[name='cheque_type'][value='"+cheque_value+"']").prop("checked",true);
var inputValue = $("input[name='cheque_type']:checked").val();
Hope this helps.
Edit: triggering not solves the value issue and I improved my answer and you can see demo of solution on link JSFiddle Demo
I've got the following code to trigger a click event on some radio buttons! but it doesn't get fired! can any one help me with this!
CODE :
$("#inline_content input[name='type']").click(function(){
if($('input:radio[name=type]:checked').val() == "walk_in"){
$('#select-table > .roomNumber').attr('enabled',false);
}
});
RADIO BUTTONS
<form class="type">
<input type="radio" name="type" checked="checked" value="guest">In House</input>
<input type="radio" name="type" value="walk_in">Walk In</input>
</form>.
Update
Tried onChange() too but not working.
It fires. Check demo http://jsfiddle.net/yeyene/kbAk3/
$("#inline_content input[name='type']").click(function(){
alert('You clicked radio!');
if($('input:radio[name=type]:checked').val() == "walk_in"){
alert($('input:radio[name=type]:checked').val());
//$('#select-table > .roomNumber').attr('enabled',false);
}
});
There are a couple of things wrong in this code:
You're using <input> the wrong way. You should use a <label> if you want to make the text behind it clickable.
It's setting the enabled attribute, which does not exist. Use disabled instead.
If it would be an attribute, it's value should not be false, use disabled="disabled" or simply disabled without a value.
If checking for someone clicking on a form event that will CHANGE it's value (like check-boxes and radio-buttons), use .change() instead.
I'm not sure what your code is supposed to do. My guess is that you want to disable the input field with class roomNumber once someone selects "Walk in" (and possibly re-enable when deselected). If so, try this code:
HTML:
<form class="type">
<p>
<input type="radio" name="type" checked="checked" id="guest" value="guest" />
<label for="guest">In House</label>
</p>
<p>
<input type="radio" name="type" id="walk_in" value="walk_in" />
<label for="walk_in">Walk in</label>
</p>
<p>
<input type="text" name="roomnumber" class="roomNumber" value="12345" />
</p>
</form>
Javascript:
$("form input:radio").change(function () {
if ($(this).val() == "walk_in") {
// Disable your roomnumber element here
$('.roomNumber').attr('disabled', 'disabled');
} else {
// Re-enable here I guess
$('.roomNumber').removeAttr('disabled');
}
});
I created a fiddle here: http://jsfiddle.net/k28xd/1/
Personally, for me, the best solution for a similar issue was:
HTML
<input type="radio" name="selectAll" value="true" />
<input type="radio" name="selectAll" value="false" />
JQuery
var $selectAll = $( "input:radio[name=selectAll]" );
$selectAll.on( "change", function() {
console.log( "selectAll: " + $(this).val() );
// or
alert( "selectAll: " + $(this).val() );
});
*The event "click" can work in place of "change" as well.
Hope this helps!
A different way
$("#inline_content input[name='type']").change(function () {
if ($(this).val() == "walk_in" && $(this).is(":checked")) {
$('#select-table > .roomNumber').attr('enabled', false);
}
});
Demo - http://jsfiddle.net/cB6xV/
Seems like you're #inline_content isn't there! Remove the jQuery-Selector or check the parent elements, maybe you have a typo or forgot to add the id.
(made you a jsfiddle, works after adding a parent <div id="inline_content">: http://jsfiddle.net/J5HdN/)
put ur js code under the form html or use $(document).ready(function(){}) and try this.
$('#inline_content input[type="radio"]').click(function(){
if($(this).val() == "walk_in"){
alert('ok');
}
});
I know nothing of JavaScript.
I had to add a group of two radio buttons to an HTML form with values "yes" and "no".
Now I need to make them "required"
There are several other required fields in the form and this piece of JavaScript:
<SCRIPT LANGUAGE="JavaScript">
<!--
reqd_fields = new Array();
reqd_fields[0] = "name";
reqd_fields[1] = "title";
reqd_fields[2] = "company";
reqd_fields[3] = "address";
reqd_fields[4] = "city";
reqd_fields[5] = "state";
reqd_fields[6] = "zip";
reqd_fields[7] = "phone";
reqd_fields[8] = "email";
reqd_fields[9] = "employee";
function validate(form_obj) {
if (test_required && !test_required(form_obj)) {
return false;
}
It was done by someone else, not me.
What I did is just added my field to this array, like this:
reqd_fields[10] = "acknowledge";
However it doesn't seem to be working.
Please guide me as I am totally ignorant when it comes to JavaScript.
Why don't you just make one selected by default then one will always be selected.
A link to your page or a sample of your HTML would make this easier, but I'm going to hazard a guess and say that the values in the array match the "name" attribute of your radio button elements.
If this the case, "acknowledge" should be the name of both radio buttons, and to make things easier, one should have the attribute "checked" set to "true" so there is a default, so you'll get a value either way.
So, something like this:
<input type="radio" name="acknowledge" value="yes" /> Yes <br/>
<input type="radio" name="acknowledge" value="no" checked="true" /> No <br/>
I know question is ancient but this is a simple solution that works.
<script type="text/javascript">
function checkForm(formname)
{
if(formname.radiobuttonname.value == '') {
alert("Error: Please select a radio button!");
return false;
}
document.getElementById('submit').value='Please wait..';void(0);
return true;
}
</script>
<form name="formname" onsubmit="return checkForm(this)"
<input type="radio" value="radio1" name="radiobuttonname" style="display:inline;"> Radio 1<br>
<input type="radio" value="radio2" name="radiobuttonname" style="display:inline;"> Radio 2<br>
<input type="submit" value="Submit">
</form>
Without seeing your HTML and more context of your validate function it's unclear exactly what you're looking for, but here's an example of how to require a selected value from a radio group:
<form name="form1">
<input type="radio" name="foo"> Foo1<br/>
<input type="radio" name="foo"> Foo2<br/>
</form>
<script type="text/javascript">
var oneFooIsSelected = function() {
var radios = document.form1.foo, i;
for (i=0; i<radios.length; i++) {
if (radios[i].checked) {
return true;
}
return false;
};
</script>
Here is a working example on jsFiddle.
I always recommend using jQuery validate seems better to me than trying to re-invent the wheel
