I'm trying to do javascript, but I'm a ruby guy and really suck with javascript. I have a one field form (text field and submit button) in which javascript only allows the form to be submitted if there is text in the field. However, I switched the field type from a text field to a select. Now, the form can't submit. I am almost certain the problem is with my javascript. Here is the code I have that word with a text field. How do I get it to work with the select?
Form:
<form id="new_skill" class="new_skill" method="post" action="/skills" >
<li>
<input id="resume-field" class="field field288" type="text"
value="Type a speciality you want to add to your profile"
title="Type a speciality you want to add to your profile"
name="skill[label]"></input>
</li>
<li>
<input class="button button-add button-add-disabled"
type="submit" value="ADD +" name="commit"></input>
</li>
</form>
Javascript:
(function($){
$(document).on('focusin', '#resume-field', function() {
$(this).parents().find('.button-add-disabled').removeClass('button-add-disabled');
}).on('focusout', '#resume-field', function(){
if(this.value==' '||this.title==this.value) {
$(this).parents().find('.button-add').addClass('button-add-disabled');
} else {
$(this).parents().find('.button-add').removeClass('button-add-disabled');
}
});
$('.button-add-disabled').click(function(){
return !$(this).hasClass('button-add-disabled');
});
}(jQuery));
css:
.button-add { width: 49px; height: 28px; border: solid 1px #8c8c8c; display: block;
font-size: 11px; line-height: 28px ; color: #fff; text-align: center;
font-family: 'Ubuntu', sans-serif; transition: none; margin: 0 0 0 auto;
border-radius: 3px; }
.button-add:hover { text-decoration: none;
-webkit-transition:none;
-moz-transition:none;
-ms-transition:none;
-o-transition:none;
transition:none;
}
.button-add-disabled { background: url(/assets/add-specialities-disabled.png)
repeat-x 0 0; box-shadow: 0 0 0 0; margin-left:35px; }
.button-add-disabled:hover { background: url(/assets/add-specialities-disabled.png)
repeat-x 0 0; box-shadow: 0 0 0 0; }
Html for form with drop down:
<select id="resume-field" name="skill[label]">
<option value="1" title="option_1"></option>
<option value="2" title="option 2" selected="selected"></option>
</select>
I made a minimal example (jsfiddle), doing what I think you asked for, but not using your code. You can probably adapt it if it does what you want.
HTML
<form>
<select id="selectme">
<option value="">-- Please select one --</option>
<option value="1">1</option>
<option value="2">Two</option>
<option value="3">III</option>
</select>
<input type="submit" value="submit" id="clickme">
</form>
JS
$(function(){
$("#clickme").prop("disabled", true);
$("#selectme").change(function(){
if ($("#selectme").val() != "") {
$("#clickme").removeAttr("disabled");
} else {
$("#clickme").prop("disabled", true);
}
});
})
CSS
#clickme {
background-color: #f00;
}
#clickme:disabled {
background-color: #eee;
}
you stated that you have switched the input field type from text to select. Therefore you need to add this kind of html:
<select>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
To start, your HTML is a little bit off:
<form id="new_skill" class="new_skill" method="post" action="/skills" >
<!-- needs a parent UL element -->
<li>
<input id="resume-field" class="field field288" type="text"
value="Type a speciality you want to add to your profile"
title="Type a speciality you want to add to your profile"
name="skill[label]"></input>
<!-- as a side not, input tags can be self-close (<input type="text" />)
</li>
<li>
<input class="button button-add button-add-disabled"
type="submit" value="ADD +" name="commit"></input>
</li>
</form>
If you've changed your input to a select element, then you need option elements, of which each can have a "value" attribute, as follows:
<select>
<option value="something">Something</option>
</select>
In the context of what you are trying to do, I'm not sure that a select element would fit your needs if you are wanting the user to type something in... You could pre-fill the select element with option elements, each corresponding to a specific "specialty that they want to add to their profile".
UPDATED and SIMPLIFIED:
Assuming that you did change the <input> elements to <select><option></select> elements, your code will work fine with only minor changes.
jsFiddle Demo
Really, you only need to track the change event:
HTML:
<form id="new_skill" class="new_skill" method="post" action="/skills" >
<li>
Select a specialty to add to your profile:<br>
<select id="resume-field" name="skill[label]">
<option value="default">Select a speciality:</option>
<option value="cod3r">Programming</option>
<option value="pizza">Pizza consumption</option>
</select>
</li>
<li>
<input class="button button-add button-add-disabled"
type="submit" value="ADD +" name="commit"></input>
</li>
</form>
javascript/jQuery:
$(document).on('change', '#resume-field', function() {
if(this.value=='default') {
$(this).parents().find('.button-add').addClass('button-add-disabled');
} else {
$(this).parents().find('.button-add').removeClass('button-add-disabled');
}
});
PS: Of course, to make the jsFiddle work I also had to temporarily remove the url() etc from your css...
