jquery将ID添加到所有段,使它们都可以链接。 [英] jquery to add ids to all paras to make them all linkable.
问题描述
我有一个拥有数千个htm文件的网站。有时我需要派人到特定的段落阅读。
我在寻找的是一个jQuery插件,它简单地为所有段落添加id,使它们可以链接,所以我们可以将它们发送到: http://www.demo.com/index.html#p_10 。
为什么选择插件?并且不需要ID
如果将脚本插入到页面或现有的外部脚本中,这应该可行
注意:这不会以任何方式修改DOM,并且会比.each更快
var pIndexPos = location.hash.indexOf(p_);
if(pIndexPos!= - 1){
var pIndex = parseInt(location .hash.substring(pIndexPos + 2),10)+1; // 1based for nnth
var offsetTop = $(p:nth-child(+ pIndex +))。offset()。top- 20; // - 项目的高度
$('html,body')。animate({
scrollTop:offsetTop
},500);
}
} );
I have a site with thousands of htm documents on them. Sometimes I need to send someone to a specific paragraph to read. What I am looking for is a jquery plugin which simply adds ids to all the paragraphs, making them linkable, so we could send them to: http://www.demo.com/index.html#p_10 for instance.
Why a plugin? And no need for an ID
This should work if you insert a script into the page or into an existing external script
NOTE: This does NOT modify the DOM in any way and is WAY faster than an .each
$(function() {
var pIndexPos = location.hash.indexOf("p_");
if (pIndexPos!=-1) {
var pIndex = parseInt(location.hash.substring(pIndexPos+2),10)+1; // 1based for nth
var offsetTop = $("p:nth-child("+pIndex+")").offset().top-20; // - height of item
$('html, body').animate({
scrollTop: offsetTop
},500);
}
});
