jquery selector needed to select all certain children of parent

由 久未见 提交于 2019-12-13 18:45:04
问题 I have a page with some tables on it. In each table the first row is normal but the rest of the rows have a class of hidden so that they are not displayed on load. In one of the cells on the first row of the table there is a link to click to view more details (fade in the hidden rows of that table). I'm struggling to get this to work though. So basically I need a selector that will find all the hidden rows that are in the same table as the element that's clicked so that they can be faded in.

When I click the next page in datatables my jquery selectors aren't working anymore

由 夙愿已清 提交于 2019-12-13 15:05:46
问题 I'm using datatables plugin for jquery to show my data on the page. I have this selector when someone clicks on a row: $('#myTable tr[class !="tableHeader"]').click(function(){ alert("clicked!"); } and everything is OK until I click on the "Next page" which shows me next 10 results - then this click function doesn't show "clicked" message box anymore no matter which row I click. I'm guessing that the problem is in a way how these new results (rows in the table) are shown, so please give me

Custom jQuery Pseudo-selector Receiving Undefined Arguments

由 五迷三道 提交于 2019-12-13 14:28:09
问题 I'm attempting to add a custom pseudo-selector to jQuery, currently using v1.8.0, based on a few different tutorials I've found. I'm essentially trying to implement a case insensitive :contains selector. My current incarnation looks like this $.expr[':'].icontains = function(obj, index, meta, stack){ return (obj.textContent || obj.innerText || jQuery(obj).text() || '').toLowerCase().indexOf(meta[3].toLowerCase()) >= 0; }; which came from this post. It seems like the selector is getting

jquery selector performance

由 放肆的年华 提交于 2019-12-13 14:19:16
问题 Is there a more performant way to write this. $('#test').find('option:selected[value!=""]') 回答1: You can tweak it at little, but using methods instead of Sizzle: $('#test').find('option').filter(function() { return this.selected && this.value.length }); Benchmark : http://jsperf.com/sizzle-vs-methods-filter/12 .filter() is about 70% faster for me. 回答2: Well, there will always only be one selected, so you don't need a find() handler in my opinion. I'll just write it like this: $('#test option

jQuery: How to find elements *without* a certain class

由 对着背影说爱祢 提交于 2019-12-13 13:08:04
问题 Why does this fail... $( 'div.contactAperson input' ).not( 'input.hadFocus' ).focus(function() { $(this).attr('value', '' ); }); ...it's meant to sniff out input's that have not got the class .hadFocus and then when one of that subset receives focus it should zap the value to null. Right now, input values are always getting zapped -- the test .not( 'input.hadFocus' ) is failing to stop execution. Btw, preceding the above code is the following code, which is working fine: $( 'div

问题 Currently I have this JQuery script var img = $(this); img.wrap('<div class="photo"></div>'); img.parent().append("<p>" + img.attr("alt") + "</p>"); which successfully turns the following: <img src="photo.jpg" alt="caption"> into this <div class="photo"> <img src="photos.jpg" alt="caption"/> <p>caption</p> </div> All is well unless the image has a link as a parent; <a href="#"><img since I want it to be correct html (I'm fussy) improving the resulting outcome bellow would be satisfactory <a
