Question

我需要一些关于此代码的帮助。我想阅读当前的网址，当网址中包含“#_ThankYou”时，我想在页面上添加一个新内容，并且该div包含一些将显示广告供应商广告的javascript。我有以下但我认为我可能陷入无限循环。不确定我是否正确编码。有人有好的建议吗？

<script type="text/javascript">
window.eddyCookieCount = 0;
window.eddyNumberAttempts = 0;
window.myInterval = setInterval(function() {
    if (window.location.href.indexOf("#_ThankYou") > window.eddyCookieCount) {
            jQuery('div.thankyou-container').append('<div>' + vm_load({
                "displayId": "12584", // Numeric unique ad display Id
                "publisherId": "33927", // Publisher ID 
                "campaign": "9380", // Numeric Publisher Campaign Id
                "maxResults": "3",
                "areaofstudy":     JSON.parse(jQuery.cookie('CategorySubCategorySpecialty')).CATEGORIES[0].text.replace('Business','1').replace('Criminal Justice & Legal','3').replace('Education','5').replace('Fine Arts & Design','2').replace('Health & Medicine','8').replace('Liberal Arts & Humanities','5').replace('Math, Science & Engineering','9').replace('Public Affairs & Social Sciences','13').replace('Religious Studies','5').replace('Technology','9').replace('Vocational Training',''),
                "md": "1"
            }) + '</div>');
    window.eddyNumberAttempts++;
    if (window.eddyNumberAttempts > 60) {
      window.eddyCookieCount = jQuery.cookie('CategorySubCategorySpecialty').length;
      window.eddyNumberAttempts = 0;
    }
  }
  else if (jQuery.cookie('CategorySubCategorySpecialty').length < window.eddyCookieCount) {
    window.eddyCookieCount = jQuery.cookie('CategorySubCategorySpecialty').length;
  }
}, 50);
</script>

Answer 1

无需间隔来监视要添加的哈希值。

$(window).on('hashchange', function() {
     if (window.location.search === "#_ThankYou") {

    }
});

在您的代码中，当您处于更改URL的状态时，我看不到您取消间隔，因此它会继续触发。你需要取消它。

window.clearInterval(window.myInterval)

Answer 2

它适用于我，我必须在视图更改时检查URL中的标记。

我的工作方式是在代码下面，这似乎不太好用，但它是基于选择器工作的：

$('.nav ul li a').click(function() {
    setTimeout(changeurl, 4000);        
});

function changeurl(title, newurl) {
    if (window.location.hash == '') {
        return window.location.hash = '#/dashboard';        
    }

    var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + window.location.hash;

    if (history.pushState) {            
        window.history.pushState({path:newurl},'',newurl);
    }
}

最后，我修改了代码：

var token = window.location.search;

$(window).on('hashchange', function() {
     if (window.location.search === token) {
         setTimeout(changeurl, 4000);
    }
});

连续检查URL直到字符串存在，找到时运行javascript代码
