I am trying to write a script that detects if a tables tds are empty and if they are hide the parent tr
I've searched Stack Overflow and found other scripts but none seem to work for me.
So far I have:
$(".table tr").each(function() {
var cell = $(this).find('td').html();
if (cell == null){
console.log('empty');
$(this).parent().addClass('nodisplay');
}
});
but just can't get it working. Any advice would be appreciated!
Try this -
$("table tr td").each(function() {
var cell = $(this);
if ($(cell).text().length == 0){
console.log('empty');
$(this).parent().addClass('nodisplay');
}
});
you should try this.
jQuery(document).ready(function(e) {
jQuery(jQuery('table tr td:empty').parents('tr')).addClass('nodisplay');
});
.html() only returns the content of the first matched element, so if your rows have more than one cell this wouldn't work. .text() might be a better fix, unless you have images or other empty tags in the cells.
$("table tr").each(function() {
var cell = $.trim($(this).find('td').text());
if (cell.length == 0){
console.log('empty');
$(this).addClass('nodisplay');
}
});
It seems you want to hide rows that have only whitespace content (but the cells might have other element child nodes). Using plain javascript:
var rows = document.getElementsByTagName('tr');
var i = rows.length;
while (i--) {
if ( !trim(getText(rows[i])) ) {
rows[i].className += ' nodisplay';
}
}
Helpers:
function trim(s) {
return s.replace(/(^\s*)|(\s*$)/g, '');
}
function getText(el) {
if (typeof el.textContent == 'string') {
return el.textContent;
} else if (typeof el.innerText == 'string') {
return el.innerText;
}
}
$('table tr').each(function(){
var hide = true;
$('td',this).each(function(){
if ($.trim($(this).text()) != "")
hide = false;
});
if(hide)
$(this).closest('tr').hide();
// OR $(this).closest('tr).addClass('nodisplay');
});
Hide table, if table have no rows using jquery
$('.tblClass').each(function(){
if($(this).find('.rows').length == 0){
$(this).hide();
}
});
<td></td>)?
