Jquery滚动到第页的锚定标记

Posted 2021-02-25

You will want to include the jquery easing plugin: http://gsgd.co.uk/sandbox/jquery/easing/

Add a class of 'scroll' to any element that should slide to an anchor tag. You must give the anchor tag an id equal to the name.

$(document).ready(function(){
	$(".scroll").click(function(event){
		//prevent the default action for the click event
		event.preventDefault();
 
		//get the full url - like mysitecom/index.htm#home
		var full_url = this.href;
 
		//split the url by # and get the anchor target name - home in mysitecom/index.htm#home
		var parts = full_url.split("#");
		var trgt = parts[1];
 
		//get the top offset of the target anchor
		var target_offset = $("#"+trgt).offset();
		var target_top = target_offset.top;
 
		//goto that anchor by setting the body scroll top to anchor top
		$('html, body').animate({scrollTop:target_top}, 2000, 'easeOutQuad');
	});
});
