網頁源代碼:
<span class="input-style">http://edge.convers....../0/299/manifest.m3u8</span>
<span hidden="true" id="cdns">http://edge.conversant.swiftserve.com/aaaa/fc-aaaa/d/5297/0/299/manifest.m3u8</span>
在selenium中用javascript的調用,代碼如下:
js.executeScript("var text= document.getElementById('cdns'); text.removeAttribute(\"hidden\"); ");
System.out.println(wd.findElement(By.xpath("//div[@id='"+distToID+"']/div/div[2]/div/span[@id='cdns']")).getAttribute("hidden"));
System.out.println(wd.findElement(By.xpath("//div[@id='"+distToID+"']/div/div/table/tbody/tr["+i+"]/th")).getText()+".m3u8 = " +wd.findElement(By.xpath("//div[@id='"+distToID+"']/div/div[2]/div/span[@id='cdns']")).getText());
console的輸出信息如下:
null //輸出hidden屬性,爲null
main.m3u8 = http://edge.conversant.swiftserve.com/aaaa/fc-aaaa/Aaaa_cdnresult/5293/0/300/manifest.m3u8 //輸出顯示的m3u8
值得注意的是,即使用document.getElementById('cdns').hidden='false' 的語句也沒有產生變化,輸出hidden=true
網上參考信息:
hidden屬性在html5中,只要存在,就是隱藏效果,而不論值爲多少
要顯示元素,要刪除hidden屬性,而不是設置爲false
