I'm using Jquery to show/hide divs based on what a user selects in a dropdown.
My HTML:
<select>
<option value='test'>Test</option>
<option value='example'>Example</option>
<option value='blah'>Blah</option>
</select>
<div data-show="blah">Should be shown when blah</div>
<div data-hide="example">Should be hidden when example</div>
My Jquery (in coffeescript):
$("select").on "change", () ->
shows = $('[data-show="' + $(this).val() + '"]')
hides = $('[data-hides="' + $(this).val() + '"]')
shows.show()
hides.hides()
This works when a user chooses the right option, say Example . But when a user goes back to say Test , it should go back to the default. How do I get this to work?
Can use filter()
to set final display and do opposite on whole group before the filter
$("select").on("change", function(){ var value = this.value // hide all data-show $('[data-show]').hide().filter(function(){ return $(this).data('show') === value; }).show()// only show matching ones $('[data-hide]').show().filter(function(){ return $(this).data('hide') === value; }).hide() }).change()
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select> <option value='test'>Test</option> <option value='example'>Example</option> <option value='blah'>Blah</option> </select> <div data-show="blah">Should be shown when blah</div> <div data-hide="example">Should be hidden when example</div>
I dont know what you are up to but this is the described behavior, probably not the desired :D
$('select').on('change', (e) => { // apply defaults, then filter // credits to filter @charlietfl $('[data-show]').hide().filter('[data-show=' + $(e.target).val() + ']').show(); $('[data-hide]').show().filter('[data-hide=' + $(e.target).val() + ']').hide(); }).change();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select> <option value='test'>Test</option> <option value='example'>Example</option> <option value='blah'>Blah</option> </select> <div data-show="blah">Should be shown when blah</div> <div data-hide="example">Should be hidden when example</div>
EDIT added default hide/show
Create a selection of your elements you want to show/hide:
var elements = $('[data-show], [data-hide]');
Then you can use jQuery's .filter
function to show only the selected element:
var elements = $('[data-show], [data-hide]'); function showElement(option) { var filter; // hide all elements befor filtering elements.hide(); // create the filter value, which will be used for filtering switch (option) { case 'test': filter = '[data-hide="example"]'; console.log('show only example'); break; case 'blah': filter = '*'; console.log('show all elements'); break; default: console.log('hide all elements (including example)'); break; } if (filter) { elements.filter(filter).show(); } } showElement('test'); $("select").on("change", function() { showElement($(this).val()); })
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select> <option value='test'>Test</option> <option value='example'>Example</option> <option value='blah'>Blah</option> </select> <div data-show="blah">Should be shown when blah</div> <div data-hide="example">Should be hidden when example</div>
Also you had several typos :
When you select the element via data-hide
, there's an additional s
( hides
):
hides = $('[data-hides="' + $(this).val() + '"]')
When you want to hide hides
via calling .hides()
, jQuery only has a .hide()
function to hide an element:
hides.hides()
<select class="selectBoxClass">
<option value='test'>Test</option>
<option value='example'>Example</option>
<option value='blah'>Blah</option>
</select>
<div data-show="blah" class="all ">Should be shown when blah</div>
<div data-hide="example" class="all">Should be hidden when example</div>
<script>
$(document).on('change', '.selectBoxClass', function(event) {
event.preventDefault();
$('div.all').show();
shows = $('[data-show="' + $(this).val() + '"]')
hides = $('[data-hides="' + $(this).val() + '"]')
shows.show()
hides.hides()
});
</script>
**if your previous code is not working well, then you can try this.
$(function(){ $('div').hide(); $('select').change(function(){ if($(this).val()=='blah'){ $('div[data-show]').show(); $('div[data-hide]').hide(); }else if($(this).val()=='example'){ $('div[data-hide]').show(); $('div[data-show]').hide(); }else{ $('div[data-hide]').hide(); $('div[data-show]').hide(); } }) })
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <select> <option value='test'>Test</option> <option value='example'>Example</option> <option value='blah'>Blah</option> </select> <div data-show="blah">Should be shown when blah</div> <div data-hide="example">Should be hidden when example</div>
Let's assume you assume a set of divs, some of which you wish to show/hide based on what you select in a dropdown list, in jQuery.
This is how it can be achieved.
The grid
<div class="row exhbitors-grid-row">
<div class="col-lg-6 col-md-6 exhibitor-grid-item" style="">
<div class="exhibitor-grid-large wow pixFadeRight" data-wow-delay="0.5s" style="visibility: visible; animation-delay: 0.5s; animation-name: pixFadeRight;">
<div class="member-avater">
<img src="#" alt="">
</div>
<div class="listing-page-exhibitor-brief wow pixFadeUp" style="visibility: visible; animation-name: pixFadeUp;">
<div class="exhibitor-details">
<input type="hidden" name="industry" class="industry Accommodation" value="Accommodation">
<h4 class="grid-exhibitor-title">Tourist Board</h4>
<strong class="grid-exhibitor-copy">Manning the Booth</strong>
<div class="grid-item-host">
<span>User</span>
<a href="bcard.pdf" target="_blank" title="Download business card"><i class="fa fa-address-card b-card-file" aria-hidden="true"></i>
</a>
</div>
</div>
</div>
</div>
</div>
<div class="col-lg-6 col-md-6 exhibitor-grid-item" style="">
<div class="exhibitor-grid-large wow pixFadeRight" data-wow-delay="0.5s" style="visibility: visible; animation-delay: 0.5s; animation-name: pixFadeRight;">
<div class="member-avater">
<img src="#" alt="">
</div>
<div class="listing-page-exhibitor-brief wow pixFadeUp" style="visibility: visible; animation-name: pixFadeUp;">
<div class="exhibitor-details">
<input type="hidden" name="industry" class="industry Airline" value="Airline">
<h4 class="grid-exhibitor-title">Tourist Board</h4>
<strong class="grid-exhibitor-copy">Manning the Booth</strong>
<div class="grid-item-host">
<span>User</span>
<a href="bcard.pdf" target="_blank" title="Download business card"><i class="fa fa-address-card b-card-file" aria-hidden="true"></i>
</a>
</div>
</div>
</div>
</div>
</div>
...
...
...
</div>
Somewhere on the page,you have a dropdown list which looks like this:
<select class="category-select" name="category-select" id="category-select">
<option value="-1">Industry </option>
<option value="1">Accommodation</option>
<option value="2">Airline</option>
<option value="3">Car Rentals</option>
<option value="4">City Tourist Board</option>
...
...
...
</select>
On change of this dropdown list, we only want to show the div that has a hidden field value value same as the selected dropdown item. Check the hidden field values above in the div .
We need a small bit of jQuery to do the magic. This is how it will look:
$(document).ready(function(){
if($(".category-select")){
$(".category-select").change(function(){
$(".exhibitor-grid-item").show();
var selectedIndustry = $(".category-select option:selected").text();
$(".exhibitor-grid-item").each(function(){
var $itemIndustry = $(this).find(".industry").val();
if($(".category-select option:selected").val() > -1){
if(selectedIndustry != $itemIndustry){
$(this).find(".industry").parent().parent().parent().parent().hide();
}
}
});
});
}
});
