Using querySelectorAll as suggested by @JanDvorak (and his answer should be accepted for thinking of that), you can write your own expression, making .is(‘:invalid’) valid ? jQuery.extend(jQuery.expr[‘:’], { invalid : function(elem, index, match){ var invalids = document.querySelectorAll(‘:invalid’), result = false, len = invalids.length; if (len) { for (var i=0; i<len; i++) { if (elem === … Read more
/** * Return true to include current element * Return false to exclude current element */ $.expr[‘:’][‘nth-of-type’] = function(elem, i, match) { if (match[3].indexOf(“n”) === -1) return i + 1 == match[3]; var parts = match[3].split(“+”); return (i + 1 – (parts[1] || 0)) % parseInt(parts[0], 10) === 0; }; Test case – (check in … Read more
If you were doing this with regex, the expression would simply be: item-\d-top Where the \d indicates any single digit (0..9), and the other characters have no special meaning (so are treated as literals). However, jQuery doesn’t currently have a regex filter (only things like start/end/contains/etc) – so you would have to create your own … Read more
There is a ‘selector’ attribute in the jQuery object, but I’m not sure it’s always available.
It is called the Attribute Starts With Selector. My example sets a red text color on the elements: $(‘[class^=”tab”]’).css(‘color’, ‘red’); jsFiddle Demo Please note that if the elements have more than one class and the other precedes the one with tab inside (class=”nyedva tab231891230″) the element won’t be selected by this selector. If you want … Read more
jQuery .data() is initially populated with values from the data- attributes, but setting it only stores the associated new value in memory. It doesn’t change the attribute in the DOM. To change the attribute, you have to use: $(‘#one, #three’).attr(‘data-test’, ‘changed’); The docs are at http://api.jquery.com/jQuery.data/
In this case you need to go up to the <tr> then use .next(), like this: $(obj).closest(‘tr’).next().find(‘.class’); Or if there may be rows in-between without the .class inside, you can use .nextAll(), like this: $(obj).closest(‘tr’).nextAll(‘:has(.class):first’).find(‘.class’);
if (!$(this).hasClass(“test”)) {
Replacing HTML will result in event handlers being unbound and replacing the entire text for an element will result in HTML markup being lost. The best approach leaves any HTML untouched, manipulating only the first text node of the matching element. To get that text node, you can use .contents() and .filter(): function wrapFirstWord () … Read more
This should help: $(‘input[type=”text”], input[type=”button”]’);
