记录前端开发过程中遇到的一个问题
-
博客新增菜单后，点击新菜单后其中的js不生效，刷新页面后才生效，这个页面是通过
<a href="xxx" target=_self>标签跳转过来的。下面上我的代码<#-- Template Name: links --> <#include "header.ftl"> <@header title="tongji"> <#if (settings.patternimg!true) && (sheet.thumbnail?? && sheet.thumbnail!='') || ((metas.ri?boolean)!true && settings.rimage_cover_sheet_open!true && settings.rimage_url?? && settings.rimage_url!='')> <div class="pattern-center-blank"></div> <div class="pattern-center"> <div class="pattern-attachment-img"> <#if (settings.patternimg!true) && (sheet.thumbnail?? && sheet.thumbnail!='')> <img class="lazyload" data-src="${sheet.thumbnail!}" src="${res_base_url!}/source/images/svg/loader/orange.progress-bar-stripe-loader.svg" onerror="imgError(this)"> <#else> <img src="${settings.rimage_url!}?sheetid=${sheet.id}&type=url&itype=${settings.rimage_cover_itype!}<#if settings.rimage_cover_itype != 'image'>&id=${(settings.rimage_cover_id)!''}</#if>" srcset="<#if settings.rimage_cover_lqip == 'loading'>${res_base_url!}/source/images/svg/loader/orange.progress-bar-stripe-loader.svg<#else>${settings.rimage_url!}?sheetid=${sheet.id}&type=url&itype=${settings.rimage_cover_itype!}<#if settings.rimage_cover_itype != 'image'>&id=${(settings.rimage_cover_id)!''}</#if>&th=150</#if>" data-srcset="${settings.rimage_url!}?sheetid=${sheet.id}&type=url&itype=${settings.rimage_cover_itype!}<#if settings.rimage_cover_itype != 'image'>&id=${(settings.rimage_cover_id)!''}</#if>&th=640 640w, ${settings.rimage_url!}?sheetid=${sheet.id}&type=url&itype=${settings.rimage_cover_itype!}<#if settings.rimage_cover_itype != 'image'>&id=${(settings.rimage_cover_id)!''}</#if>&th=960 960w, ${settings.rimage_url!}?sheetid=${sheet.id}&type=url&itype=${settings.rimage_cover_itype!}<#if settings.rimage_cover_itype != 'image'>&id=${(settings.rimage_cover_id)!''}</#if>&th=1280 1280w, ${settings.rimage_url!}?sheetid=${sheet.id}&type=url&itype=${settings.rimage_cover_itype!}<#if settings.rimage_cover_itype != 'image'>&id=${(settings.rimage_cover_id)!''}</#if> 1440w" data-sizes="auto" class="lazyload<#if settings.rimage_cover_lqip == 'lowquality'> blur-up</#if>" /> </#if> </div> <header class="pattern-header"> <h1 class="entry-title">${sheet.title!}</h1> </header> </div> <#else> <div class="blank"></div> <header class="entry-header"> <h1 class="entry-title"> <#if options.links_title?default("")?trim?length gt 1> <span>${options.links_title}</span> <#else> <span class="i18n" data-iname="page.links.title"></span> </#if> </h1> </header><!-- .entry-header --> <style> .toc-container { top: 210px;

通过看代码知道了这个页面的上半部分和下半部分都是引用父类的部分。然后看下
target的几个属性的含义：
- 大概能看出来了，我第一次点击菜单的时候，超链接
target=_self不会重新执行框架，所以我在页面写的js函数不会执行了，这也就是造成第一次不刷新,刷新一次才生效。 - 怎么改呢？只需要将
target=_top就可以，因为它是重新加载的。
