Question

我遇到Xpath问题。

我有：

<ul unselectable="on" class="k-list k-reset" tabindex="-1" role="listbox" aria-hidden="true" id="1 (fix but random)" aria-live="off" style="overflow: auto;">
<li tabindex="-1" role="option" unselectable="on" class="k-item"></li>
<li tabindex="-1" role="option" unselectable="on" class="k-item">standard 2014</li>
<li tabindex="-1" role="option" unselectable="on" class="k-item k-state-selected k-state-focused" id="1 (fix but random)__PackageId_option_selected" aria-selected="true">standard couple 2014</li><li tabindex="-1" role="option" unselectable="on" class="k-item">Gratuit</li>
</ul>

<ul unselectable="on" class="k-list k-reset" tabindex="-1" role="listbox" aria-hidden="true" id="2 (fix but random)" aria-live="off" style="overflow: auto;">
<li tabindex="-1" role="option" unselectable="on" class="k-item"></li>
<li tabindex="-1" role="option" unselectable="on" class="k-item">standard 2014</li>
<li tabindex="-1" role="option" unselectable="on" class="k-item k-state-selected k-state-focused" id="1 (fix but random)__PackageId_option_selected" aria-selected="true">standard couple 2014</li><li tabindex="-1" role="option" unselectable="on" class="k-item">Gratuit</li>
</ul>

<ul unselectable="on" class="k-list k-reset" tabindex="-1" role="listbox" aria-hidden="true" id="RANDOM" aria-live="off" style="overflow: auto;">
<li tabindex="-1" role="option" unselectable="on" class="k-item"></li>
<li tabindex="-1" role="option" unselectable="on" class="k-item">standard 2014</li>
<li tabindex="-1" role="option" unselectable="on" class="k-item k-state-selected k-state-focused" id="1 RANDOM__PackageId_option_selected" aria-selected="true">standard couple 2014</li><li tabindex="-1" role="option" unselectable="on" class="k-item">Gratuit</li>
</ul>

我的问题很简单：如何在最后一次点击casper＆lt; li>标准2014？我试着这样说：

var x = require('casper').selectXPath;
this.click(x('//*ul[@class="k-list k-reset"]/li[text() = "standard 2014"]'))

但casperjs找不到。谢谢你的帮助！

Answer 1

尝试在括号中包围xpath并在末尾添加[last()]。与(xpath)[last()]

一样

您还应该从//*ul

中删除星号

它应该是这样的：

this.click(x('(//ul[@class="k-list k-reset"]/li[text() = "standard 2014"])[last()]'))

Answer 2

您应该尝试在浏览器的控制台中检查您的X路径是否有效。像

$x('//a[contains(text(),"Cancel")]')

Xpath CasperJS，取最后一个元素
