I am having trouble getting this jQuery script to function:
$(document).on('knack-scene-render.scene_126', function() {
$('#view_498 > div.kn-list-content.columns.is-multiline').each(function(index) {
if ($(this).eq(index).find('.field_744 .kn-detail-body').text().length > 0) {
$(this).eq(index).find('.field_396 .kn-detail-body').css('background-color','#ffff00');
}
});
});
The goal is to search each div group under "#view_498 > div.kn-list-content.columns.is-multiline" to see if the text value of '.field_744 .kn-detail-body' is not empty, if it's not empty, then it puts a yellow highlight on '.field_396 .kn-detail-body' in that respective div. The problem I'm having is every single '.field_396 .kn-detail-body' in all divs under the parent are being highlighted, even if there is no text in field_744 of that respective div.
What am I doing wrong?
Within the .each() callback, this refers to the current iteration element. You don't need .eq(index). After the first iteration, .eq(index) was returning an empty set
//$(document).on('knack-scene-render.scene_126', function() {
$('#view_498 > div.kn-list-content.columns.is-multiline').each(function() {
const $this = $(this) // no need to keep jQuery-ing this
if ($this.find(".field_744 .kn-detail-body").text().length > 0) {
$this.find(".field_396 .kn-detail-body").css('background-color', '#ffff00');
}
});
//});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.slim.min.js"></script>
