Question

我正在使用Struts2链接创建一个标题，但不知何故我遇到了一个非常奇怪的问题，因为我在标题中输入Struts2 a href链接遇到语法错误：jquery中无法识别的表达式错误。但是如果我没有把标题标记放在我输入的链接上就行了。有人遇到过这个问题吗？我正在使用jquery 1.11。

<%@ page language="java" contentType="text/html;" %>
  <%@ taglib prefix="s" uri="/struts-tags" %>
    <!-- this part the link would work -->
    <div class="container">
      <nav class="pull-left">
        <ul class="list-unstyled">
          <li class="animated wow fadeInLeft" data-wow-delay="0s">Inventory</li>
          <li class="animated wow fadeInLeft">
            <s:url namespace="/sales" action="saleshome" var="aURL2" />
            <s:a href="%{aURL2}">Test</s:a>
          </li>
          <li class="animated wow fadeInLeft" data-wow-delay=".2s">Purchase</li>

      </nav>

我遇到以下错误。

我认为以下可能是其原因。 var section = $（this）.attr（＆＃39; href＆＃39;）;看起来链接的代码部分导致了问题。

$(document).ready(function(){

    //Navigation menu scrollTo
    $('header nav ul li a').click(function(event){
        event.preventDefault();
        var section = $(this).attr('href');
        var section_pos = $(section).position();

        if(section_pos){
            $(window).scrollTo({top:section_pos.top, left:'0px'}, 1000);
        }

    });

    $('.app_link').click(function(e){
        event.preventDefault();
        $(window).scrollTo({top:$("#hero").position().top, left:'0px'}, 1000);      
    });

    //Show & Hide menu on mobile
    $('.burger_icon').click(function(){
        $('header nav').toggleClass('show');
        $('header .burger_icon').toggleClass('active');
    });

    //wow.js on scroll animations initialization
    wow = new WOW(
        {
          animateClass: 'animated',
          mobile: false,
          offset: 50
        }
    );
    wow.init();

    //parallax effect initialization
    $('.hero').parallax("50%", 0.3);

    //Nice scroll initialization
    $("html").niceScroll({
        scrollspeed: 50,
        autohidemode : false,
        cursorwidth : 8,
        cursorborderradius: 8,
        cursorborder : "0",
        background : "rgba(48, 48, 48, .4)",
        cursorcolor : '#1f1f1f',
        zindex : 999
    });

    //Testimonials slider initialization
    $("#tslider").owlCarousel({
        items : 1,
        navigation : true,
        pagination : false,
        slideSpeed : 300,
        paginationSpeed : 400,
        singleItem: true,
        responsive: true,
        autoPlay : true,
        transitionStyle : "fade"
    });

    //Mailchimp subscription form initialization
    $('#submit_form').submit(function(){
        $('#mc_submit').attr('disabled', 'disabled');       
        processing('icon', 'loading');
    });

    if($('#submit_form').length){
        //Mailchim Subscription form
        $('#submit_form').ajaxChimp({
            callback: chimpResponce
        });
    }   

    //Mail chimp callback function
    function chimpResponce(resp) {
        if (resp.result === 'success') {            
            processing('loading', 'icon');
            $('#mc_submit').removeAttr('disabled', 'disabled');
            $('#submit_form #mc-email').val('');
            $('#error_msg').hide();
            $('#success_msg').show();
        }else{      
            processing('loading', 'icon');
            $('#success_msg').hide();
            $('#error_msg').show();
            $('#mc_submit').removeAttr('disabled', 'disabled');
        }
    }

    function processing(hide, show){
            $('#mc_submit i').removeClass(hide).addClass(show);
    }

    //Popup video
    $('#play_video').click(function(e){
        e.preventDefault(); 

        var video_link = $(this).data('video');
        video_link = '<iframe src="' + video_link + '" width="500" height="208" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>';

        $('.about_video').append(video_link).fadeIn(200);
    });

    $('.close_video').click(function(e){
        e.preventDefault(); 

        $('.about_video').fadeOut(200,function(){
            $('iframe', this).remove();
        });

    });

});

错误描述很简单：jQuery不能使用表达式/easyaccount/sales/saleshome作为$(...)内的选择器。

您正在使用scrollTo滚动到各个部分。似乎沿着锚链接（href="#somewhere"）你也有完整网址的链接。很明显，普通的URL不能用作jQuery选择器，所以你必须过滤事件处理程序中的链接。

$('header nav ul li a').click(function(event){

    var section = $(this).attr('href');

    if (section[0] !== "#") return; // drop the link if the first char is not #

    var section_pos = $(section).position();

    if(section_pos){
        $(window).scrollTo({top:section_pos.top, left:'0px'}, 1000);
    }

    event.preventDefault();

});

href链接在标头标记中不起作用
