jquery-selectors

问题 I am clicking a submit button using this: $('input[type=submit]').click(); The problem is that I have more that 1 submit button on my page so I need to target a specific submit button. How could I do that? 回答1: If you know the number of submit inputs and which one (in order) you want to trigger a click on then you can use nth-child() syntax to target it. Or add an ID or a class to each one that separates them from the other. Selecting the elements by their index: $('input[type="submit"]:nth

In reality, it executes without generating an error, but doesn't remove any rows from the table. What am I

问题 I was experimenting with jQuery and came across a question. Can I use an actual selector with existing element as a combined selector for jQuery? So, suppose I've created a DIV element on-the-fly: var $div = $('<div>') .css('position', 'absolute') .hide(); // Just to be short $('body').append($div); And I want to show it when user hovers over P elements / paragraphs (at the cursor position): $('p').hover(function(e) { // Change the position of $div with regards of cursor position $div.show();
