问题 I want to replace <div class="blog">Blog</h1> with <h1>Blog</h1> which is inside a class name "sidebar" I used this code but didn't work: $(window).load(function() { $( ".sidebar h1" ).replaceWith( "<div class="blog">Blog</h1>" ); } What is wrong on my code? 回答1: If you want double quotes within a string that is delimited by double quotes, you must escape them with a backslash: "<div class=\"blog\">Blog</h1>" Many programmers use single quotes for JavaScript strings, which makes it easier to

问题 I am initializing a jquery ui slider that has for example a value of .01, a min of .01, and a max of 5000. My issue is that the max is stopping at 4999.990000000001.

The easiest way to fix it would to use integers instead: $(

问题 I've got this test page going on: http://joshuacody.net/qworky/ Warning: Tons of CSS3. This will only look right in Safari or Chrome. Firefox will be tolerable. All else will be lost. Essentially, when I hover on someone's name, I'd like it to trigger the hover state on their image as well. It's working now, but I feel the solution is inelegant. I'd rather not add more classes. Here it is: $('a.name_link').hover(function(){ $(this).parent('p').siblings('img').toggleClass('link_hover'); }); $(

问题 I want to sort my column by date: var table = $('#table').DataTable({ "order": [[0, "desc"]], }); But here is my result: 29.06.17 27.06.17 26.06.17 22.08.17 18.10.17 15.09.17 What I would expect is this: 18.10.17 15.09.17 22.08.17 29.06.17 27.06.17 26.06.17 June, then August, then September and then October.... I tested also: "columnDefs": [ { "type": "date-dd.mm.yy", targets: 0 } ], But this didn't change anything. 回答1: dataTables date type uses Data.parse() which only supports a limited set

问题 Using v 2.0.5 of tableSorter with the tablesorterPager plug in. I'm loading table rows with ajax (using the initial config found in the documentation, with minor changes to the ajax URL to suit my needs). Everything works great.

问题 I am building a weather station that will update the weather in "real-time" to a MySQL Database.

I would like to set up a way for a website to view this change in realtime without refreshing the page. I have tried researching a lot, but I can't quite find what I am looking for (at least with more of an explanation into
