$("tagnamehere")
所以:
$("div").each(function() {
// do something exciting with each div
$(this).css("border", "1px solid red");
// do something by directly manipulating the wrapped DOM element
this.style.border = "1px solid red";
// do something only if this particular div has a class of 'pretty'
if($(this).hasClass("pretty")) {
$(this).text("I am the pretty one");
}
});
或只是:
// apply some css to all div elements
$("div").css("border", "1px solid red");
请记住,当您使用jQuery选择多个元素时,例如: $(span)
,您在对象上调用的任何方法都将发生在所有匹配的元素上。将其视为隐式迭代 - 例如 $(span)。hide();
将隐藏页面上的所有span元素。
Keep in mind that when you use jQuery to select a number of elements, e.g. $("span")
, any method you invoke on the object will happen on all matched elements. Think of it as 'implicit iteration' - e.g. $("span").hide();
will hide all span elements on the page.
