语法:选择按钮标签的语法是
$("button")

jQuery 过滤器:此方法用于指定 HTML 元素的条件。 Filter() 方法返回符合特定条件的元素。
句法:
$(selector).filter(criteria, function(index))
例子:
HTML
Jquery Filter
My name is Donald.
Geeks
SkeeG
For
roF
Geeks
输出:过滤器搜索活动类标签并为它们着色。
jQuery 中 selector 和 filter() 的主要区别: Syntax to use it is as follows: $(“button”) selects all buttons of the HTML page. Syntax to use it as follows: $(button).filter(criteria, function(index)) selects buttons having criteria and applies function on it. Selector in jQuery filter() n jQuery jQuery selector selects all elements based on the elements name given by you. jQuery filter( ) adds further detail to the selected elements by specifying the criteria of selection. It works independently of filter( ), which means there is no need to use it along with the filter( ) method. It works along with the selector. By combining filters with your selectors, we can work to much high degree of precision.
