标签:checkbox 产生 trim scrollto ace get sel white first
比如:
$("#test").html() 意思是指:获取ID为test的元素内的html代码。其中html()是jQuery里的方法
这段代码等同于用DOM实现代码: document.getElementById(" test ").innerHTML;
虽然jQuery对象是包装DOM对象后产生的,但是jQuery无法使用DOM对象的任何方法,同理DOM对象也不能使用jQuery里的方法.乱使用会报错
约定:
如果获取的是 jQuery 对象, 那么要在变量前面加上$.
var $variable = jQuery 对象
var variable = DOM 对象
基本语法:
$(selector).action()
$(".test").next() $(".test").nextAll() $(".test").nextUntil()
$("div").prev() $("div").prevAll() $("div").prevUntil()
$(".test").parent() $(".test").parents() $(".test").parentUntil()
$("div").siblings()
