I want to find the closest span
with class error_span
. How can I do that using jQuery?
<div class="form-group row">
<div class="col-sm-4">
<label for="reimburse_price" class="control label">Amount</label>
</div>
<div class="col-sm-8">
<div>
<input type="text" name="reimburse_price" min="1" placeholder='0.00' class="form-control numberOnly" id="reimburse_price" required>
</div>
<div>
<span class="small text-danger error_span"></span>
</div>
</div>
</div>
My javascript is here
$("#reimburse_price").blur(function(){
checkNumInput("#reimburse_price");
});
My jquery function is here
function checkNumInput(id){
if ($(id).val() == "") {
$(id)[0].setCustomValidity('Please fill out this field');
$(id).closest("span .error_span").text("Please fill out this field").removeClass("hidden").addClass("text-danger");
}
}
The issue with your current code is that closest()
looks at parent elements, yet the span
you want to find is a child of a parent's sibling to the input
.
To solve your issue traverse to a common parent of both the input
and span
and use find()
from there. Try this:
$("#reimburse_price").blur(function() {
checkNumInput('#' + this.id);
});
function checkNumInput(id) {
var $input = $(id);
if ($input.val() == "") {
$input.get(0).setCustomValidity('Please fill out this field');
$input.closest('.form-group').find('.error_span').text("Please fill out this field").toggleClass("hidden text-danger");
}
}
