I have two text fields like so:
<label for="origin2">
<g:message code="api.origin2.label" default="2nd Origin" />
</label>
<g:textField class="form-control" name="origin2" value="${apiInstance?.origin2}"/>
<label for="destination2">
<g:message code="api.destination2.label" default="2nd Destination" />
</label>
<g:textField class="form-control" name="destination2" value="${apiInstance?.destination2}"/>
First question (I;m new to this), how do I initially disable these text fields?
Second question, I have a checkbox:
<label for="multicity">
<g:message code="api.multicity.label" default="Multi-City" />
</label>
<g:checkBox id="multicity" onClick="toggle('multicity', 'origin2')" name="multicity" value="${apiInstance?.multicity}" checked="${false}" />
Ideally I'd like to have the above two text boxes suddenly appear if this checkbox is checked (true) but if that can't be done I just want to enable them.
How do I do this? All help vastly appreciated.
It's very simple just add readonly attr to your input field like this.
<input type="text" name="lname" readonly>
And then add your script e.g
$("#checkbox").click(() => {
$("#field1, #field2").removeAttr("readonly")
})

I have this code snippet:
<div>
<label for="requiredSize">Required Size 5 : </label>
<input type="text" name="requiredSize" id="requiredSize" class="required_size" minlength="5" />
</div>
I am doing a form validation exercise, and I need to have one of the requirements be based on required size. How can I call the minlength into my JavaScript file to be used, since it does change throughout the form?
I have tried document.querySelector("minlength") to try and save it as a variable, but it wasn't being recognized.
const input = document.querySelector("#requiredSize");
console.log(input.getAttribute('minlength'))
<div>
<label for="requiredSize">Required Size 5 : </label>
<input type="text" name="requiredSize" id="requiredSize" class="required_size" minlength="5" />
</div>
I am trying to use the innerHTML method on an input tag and all i get back is a blank string. Here is the code i am useing.
javascript
function setName(ID){
document.getElementById('searchtitle').innerHTML = "Enter " + ID.innerHTML;
}
HTML
<input type="radio" name="searchtype" id="test" value="name" onclick="setName(this)">Last Name</input><br/>
<input type="radio" name="searchtype" value="phonenumber" onclick="setName(this)">Phone Number</input><br/>
<label for="inputfield" id="searchtitle" style="font-size:2em;">Enter Last Name</label><br/>
<input type="text" name="inputfield" id="inputfield" style="font-size:2em;"></input>
What is supposed to happen is depending on which radio button I pick the label for the input box should change. I can make the label.innerHTML=radio.value but the values are named for my php code and not formated nicely(ie. phonenumber vs. Phone Number) this is why I am trying to use the innerHTML of the radio button.
Any help I could get would be greatly appriciated.
you should embed input inside of label tag. input tag should closed by />. It's semantic HTML. When you do this clicking on label activate the input. InnerHTML only works for label then. It will return you label value.
<label for="inputfield" id="searchtitle" style="font-size:2em;">Enter Last Name
<input type="text" name="inputfield" id="inputfield" style="font-size:2em;" />
</label>
JavaScript:
console.log(document.getElementById('searchtitle').innerHTML); // returns 'Enter Last Name'
If you want the value of an input tag, you want to use .value.
First, add labels around your inputs. Second, use getName(this.parentNode). Finally, call innerText instead of innerHtml.
<html>
<head>
<script>
function setName(el){
document.getElementById('searchtitle').innerHTML = "Enter " + el.innerText;
}
</script>
</head>
<body>
<label><input type="radio" name="searchtype" value="name" onclick="setName(this.parentNode)"/>Last
Name</label><br/>
<label><input type="radio" name="searchtype" value="phonenumber" onclick="setName(this.parentNode)"/>Phone
Number</label><br/>
<label for="inputfield" id="searchtitle" style="font-size:2em;">Enter Last Name</label><br/>
<input type="text" name="inputfield" id="inputfield" style="font-size:2em;"></input>
</body>
</html>
Complete edit.
Ok, I figured out what you were looking for. First off, you've got to fix your HTML (don't put text inside of an input... and don't next an input inside of a label).
<label for="test">Last Name</label>
<input type="radio" name="searchtype" id="test" value="name" onclick="setName(this)" />
<br/>
<label for="test2">Phone Number</label>
<input type="radio" id="test2" name="searchtype" value="phonenumber" onclick="setName(this)" />
<br/>
<label for="inputfield" id="searchtitle" style="font-size:2em;">Enter Last Name</label>
<br/>
<input type="text" name="inputfield" id="inputfield" style="font-size:2em;" />
JavaScript (in Jquery, for brevity):
function setName(elem)
{
$('#searchtitle').html('Enter ' + $('label[for="'+elem.id+'"]').html());
}
You have closed the Input tag improperly with </input>
this should be
<input type="radio" name="searchtype" id="test" value="name" onclick="setName(this)"/>Last Name<br/>
<input type="radio" name="searchtype" value="phonenumber" onclick="setName(this)"/>Phone Number<br/>
I have no idea what I'm doing wrong here. I have a form with radio buttons and simple text fields. I'm checking to see if there is a value within the form fields or if either of the radio buttons have been checked. If there is no value add a red color to the label. If they have a value I'm adding back the default black. But for some reason no matter if I put a value in the text field it stays red. Also kind of strange but if I check the first checkbox the black text appears. Any help is greatly appreciated.
JS Fiddle: http://jsfiddle.net/5Sacj/
<form name="headerForm">
<label id="gender" for="gender">Gender</label>
<input type="radio" name="customer" value="male" />Male
<input type="radio" name="customer" value="female" />Female
<br/>
<label for="fname">*First Name</label>
<input type="text" class="text" id="fname" name="fname" />
<br/>
<label for="fname">*Last Name</label>
<input type="text" class="text" id="lname" name="lname" />
<input id="submit" type="submit" name="submit" value="submit"
</form>
JQUERY
$(document).ready(function() {
$("#submit").on('click', function() {
$(":text, :radio").each(function() {
if($(this).val() === '' || !$(this).is(':checked')){
$(this).prev('label').css('color','red');
} else {
$(this).prev('label').css('color','black');
}
});
});
});
That is because you are using or operator ||.
It will execute even if one is true. Try using && or have separate if condition for both.
How do I validate that the input text corresponding to the radio option is checked?
For example, using the image above:
If Contact 1's E-Mail radio option is selected, Contact 1's E-Mail text field cannot be blank, but Contact 1's Phone and US Mail text fields are still permitted.
If Contact 2's US Mail radio option is selected, Contact 2's US Mail text field cannot be blank, but Contact 2's Phone and E-Mail text fields are still permitted.
I have built the form above using the HTML below, but you can play with my Fiddle here: fiddle.
BEGIN UPDATE: I have a newer fiddle with better code here:
fiddle2
It has more instructions in the HTML and a closer attempt at my jQuery. For some reason, though, it still does not seem to be doing anything.
END UPDATE
I have tried naming the fields so that my jQuery can parse them, but that does not mean there is not a better way.
<body>
<form name="jp2code" action="#" method="POST">
<fieldset>
<legend>Contact 1</legend>
<span>
<input type="radio" id="group1_PhoneRadio" name="group1"/>
<label for="group1_PhoneText">Phone:</label>
<input type="text" id="group1_PhoneText" name="group1_PhoneText"/>
<br/>
<input type="radio" id="group1_EMailRadio" name="group1"/>
<label for="group1_EMailText">E-Mail:</label>
<input type="text" id="group1_EMailText" name="group1_EMailText"/>
<br/>
<input type="radio" id="group1_USMailRadio" name="group1"/>
<label for="group1_USMailText">US Mail:</label>
<input type="text" id="group1_USMailText" name="group1_USMailText"/>
</span>
</fieldset>
<fieldset>
<legend>Contact 2</legend>
<span>
<input type="radio" id="group2_PhoneRadio" name="group2"/>
<label for="group2_PhoneText">Phone:</label>
<input type="text" id="group2_PhoneText" name="group2_PhoneText"/>
<br/>
<input type="radio" id="group2_EMailRadio" name="group2"/>
<label for="group2_EMailText">E-Mail:</label>

<br/>

<label for="group2_USMailText">US Mail:</label>
<input type="text" id="group2_USMailText" name="group2_USMailText"/>

What is the best way to write the jQuery?
I am new to jQuery, but I attempted my hand at it based on some Show/hide examples.
What I created below does not work, but hopefully indicates what I am trying to accomplish.
$(function() {
$("input[type='radio']").change(function() { // when a radio button in the group changes
var id = $(this).id;
var index = id.indexOf('group');
if (index == 0) { // is there a better way to do this?
var groupN_Len = 7; // Length of 'groupN_'
var radio_Len = 5; // Length of 'radio'
var preStr = id.substring(0, groupN_Len);
$"input[name*='preStr']".validate = null; // clear validation for all text inputs in the group
var postStr = id.substring(groupN_Len + 1, id.Length() + 1 - radio_Len); // extract Phone, EMail, or USMail
$(preStr+postStr+'Text').validate({ rules: { name: { required: true } } });
}
});
});
To make sure that the radiobutton is checked for each field, add attribute required="" in one of the radiobuttons for each fieldset.
demo
OK, whatever radio button is selected in the Contact Group's Contact Preferences, that corresponding text field is required.
Here is where I am so far on my jQuery checking:
EDIT:
Modified with tilda's important detail about adding '.' to the class name.
Added Required Attribute: how to dynamically add REQUIRED attribute to textarea tag using jquery?
Removed Required Attribute: jquery removing html5 required attribute
Final code works and looks like this:
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.js"></script>
<script type="text/javascript">
$(function() {
jQuery.validator.setDefaults({
debug: true,
success: "valid"
});
$("input[type='radio']").change(function() {
$('.'+$(this).attr('name')).each(function(index) {
$(this).removeAttr('required');
});
if($(this).is(':checked')) {
$('.'+$(this).attr('id')).each(function(index) {
$(this).prop('required',true);
});
}
});
$('#submit').click(function() {
$(this).validate();
});
});
Back to the HTML of the document: I did a lot of subtle editing to the text by creating specific ids and names for the radio buttons that matched up with the class names for the text controls.
Here is that end result:
<body>
<form name="jp2code" action="#" method="POST">
<div>For each field below, provide the Phone Number, E-Mail Address, and Street Address. <b>Indicate the preferred contact method using the radio button.</b></div>
<fieldset>
<legend>Contact 1</legend>
<span>
<input type="radio" id="group1_Phone" name="group1"/>
<label for="group1_Phone">Phone:</label>
<input type="text" name="group1_PhoneText" class="group1 group1_Phone" />
<br/>
<input type="radio" id="group1_EMail" name="group1"/>
<label for="group1_EMail">E-Mail:</label>
<input type="text" name="group1_EMailText" class="group1 group1_EMail" />
<br/>
<input type="radio" id="group1_USMail" name="group1"/>
<label for="group1_USMail">US Mail:</label>
<input type="text" name="group1_USMailText" class="group1 group1_USMail" />
</span>
</fieldset>
<fieldset>
<legend>Contact 2</legend>
<span>
<input type="radio" id="group2_Phone" name="group2"/>
<label for="group2_Phone">Phone:</label>
<input type="text" name="group2_PhoneText" class="group2 group2_Phone" />
<br/>
<input type="radio" id="group2_EMail" name="group2"/>
<label for="group2_EMail">E-Mail:</label>
<input type="text" name="group2_EMailText" class="group2 group2_EMail" />
<br/>
<input type="radio" id="group2_USMail" name="group2"/>
<label for="group2_USMail">US Mail:</label>
<input type="text" name="group2_USMailText" class="group2 group2_USMail" />
</span>
</fieldset>
<div>
<input type="submit" value="Send" id="submit"/>
</div>
</form>
</body>
Let me explain what is going on in the jQuery, using the HTML above:
When a radio button's checked state changes, each control with a class name that matches the radio button's name attribute has the required property removed.
If a radio button is checked (i.e. checked=true), then each control with a class name that matches the radio button's id attribute has the required property added.
Finally, the validator seems to have to be run on a single form control (not on individual text controls like I was doing).
Here is the sample Fiddle that I ended with: Fiddle v8
At tilda: You didn't say much, but what you did say helped a lot!
I've got an HTML form that's built dynamically using templates at runtime - dictated by user action.
I need to set the tab index across the form based on the tabindexing specified within each of the pieces of the form.
Given this, is there a way in jQuery to order items within a set? For instance something that follows this pseudo structure would be awesome, but I can't figure out how to achieve it:
<div name="firstTemplate" templateIndex="0">
<input type="text" name="field0" tabIndex="1" />
<input type="text" name="field1" tabIndex="2" />
<input type="text" name="field2" tabIndex="3" />
</div>
<div name="firstTemplateRpt" templateIndex="1">
<input type="text" name="field0" tabIndex="1" />
<input type="text" name="field1" tabIndex="2" />
<input type="text" name="field2" tabIndex="3" />
</div>
<div name="secondTemplate" templateIndex="2">
<input type="text" name="field0" tabIndex="1" />
<input type="text" name="field1" tabIndex="2" />
<input type="text" name="field2" tabIndex="3" />
</div>
I could then use some variation of the following concept:
$("input, textarea, select, input:checkbox, input:radio").orderBy("templateIndex, tabIndex");
Where templateIndex would be the index of the template within the form and the tabindex would be the tabindex of the control within the template. A template could be added to the form multiple times at runtime, which is causing havoc on manually specified tabindexes.
When another template is added to the form, it would be assigned the templateIndex="3" with its manually set tabIndexes starting again at 1.
Collect the divs with a templateIndex attribute into an array, then sort them like:
divArray.sort(function(a, b) {
return a.getAttribute('templateIndex') - b.getAttribute('templateIndex');
});
Then iterate over those and sort the inputs inside the array using a very similar function:
inpArray.sort(function(a, b) {
return a.tabIndex - b.tabIndex;
});
Then move the elements in the required order in the document using something like node.parentNode.insertBefore(node, firstChild).
