How to define an onclick function on Laravel Collectives? - laravel

Question

I have implemented a drop down using Laravel collectives. I need to call function setMaterialValue(let x){ console.log(x)} on each time I select a material. This should be specific to each material as cotton-10, wetlook-20, crocodile-30 etc. Without Laravel collective this can be performed as
<option onclick="setMaterialValue(10);">Cotton</option>
How to perform this using Laravel collectives?
My code is as follows:
<div class="card">
<div class="card-header"><h2 class="card-title m-0">Feature Selector</h2></div>
<div class="card-body">
<h5 class="card-title"><b>Material Selector</b></h5>
<div class="row">
<div class="col-md-6">
Textile Material
</div>
<div class="col-md-6">
{{Form::select('material_selector', [
'10' => 'Cotton',
'20' => 'Wet Look',
'30' => 'Crocodile',
], null, ['placeholder' => 'Select Material'],['class'=>'form-control'])
}}
</div>
</div>
<hr>
</div>
</div>

Answer 1

FYI - Where your class declaration is add it and any other html attributes there as well:
{{ Form::select('material_selector',
[
'1' => 'Cotton',
'2' => 'Wet Look',
'3' => 'Crocodile',
],
null,
['placeholder' => 'Select Material'],
[
'class'=>'form-control',
'onclick'=>'setMaterialValue(10)' // <== ADD IT HERE
])
}}

You should probably use jQuery. Then you can address your select element as follows
$(document).ready(function() {
$('.form-control[name="material_selector"]').on('change', showSelectedValue);
function showSelectedValue(event) {
var target = $(event.target);
console.log(target.val() + " = " + target.find('option:selected').text());
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="material_selector" class="form-control">
<option value="10">Cotton</option>
<option value="20">Wet Look</option>
<option value="30">Crocodile</option>
</select>
Another option
If you really do not want to use jQuery, then try to use the onChange attribute for the select tag like the example below
{{Form::select(
'material_selector', // name attribute of the select
['10' => 'Cotton', '20' => 'Wet Look', '30' => 'Crocodile'], // option values
null, // selected value, for example '20'
['placeholder' => 'Select Material', 'class' => 'form-control', 'onChange' => 'showSelectedValue(this)'], // attributes for <select>
)}}
function showSelectedValue(element) {
console.log(element.value + " = " + element.options[element.selectedIndex].text);
}
<select name="material_selector" class="form-control" onChange="showSelectedValue(this)">
<option value="10">Cotton</option>
<option value="20">Wet Look</option>
<option value="30">Crocodile</option>
</select>
