Javascript链接在Selenium Excel VBA中无响应 [英] Javascript link doesn't respond in selenium excel vba

问题描述

我正在尝试点击JavaScript链接这样的行

I am trying to do such a line that clicks on a javascript link

.FindElementById("ctl00_ContentPlaceHolder1_LinkButton4").WaitDisplayed(True, 3000).Click

此行没有任何错误，但有时它不起作用..我说有时不总是..有时是工作，有时是停止，我不知道原因我必须重新启动代码才能启动新的bot(驱动程序)，在某些情况下，我必须重新启动很多次，直到此链接正常工作

There's no any errors at this line but sometimes it doesn't work .. I say sometimes not always.. sometimes work and sometimes stopped and I don't know the reason I have to restart the code to start new bot (driver) and at some cases I have to restart so many times till this link worked

这是此javascript链接的html部分

Here's the html part of this javascript link

<a id="ctl00_ContentPlaceHolder1_LinkButton4" href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$LinkButton4','')" style="display:inline-block;width:280px;text-decoration:none;height:22px;font-weight:bold;font-size:11pt;color:Maroon;border-width:1px;border-style:Dashed;border-color:#404040;background-color:#FFFFC0;vertical-align: middle; text-align: center; cursor: hand;">Some Text Removed For Privacy</a>

如何使此链接正常工作?或者有没有变通的方法来使其正常工作..?我试图解决这一问题，但根本没有发现任何线索

How can I make this link work ... or is there a workaround to make it work ..? I tried to solve that point but I didn't find any clue at all

这是响应式部分的html部分(我看不出任何区别)

This is the html part for a responsive one (I don't see any difference)

<a id="ctl00_ContentPlaceHolder1_LinkButton4" href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$LinkButton4','')" style="display:inline-block;width:280px;text-decoration:none;height:22px;font-weight:bold;font-size:11pt;color:Maroon;border-width:1px;border-style:Dashed;border-color:#404040;background-color:#FFFFC0;vertical-align: middle; text-align: center; cursor: hand;">Some Text Removed For Privacy/a>

这是执行此行后的错误快照

Here's a snapshot of the error after executing this line

.ExecuteScript "javascript:__doPostBack('ctl00$ContentPlaceHolder1$LinkButton4'"

这是网络快照(可能有用)>>我看到302(我认为应该有更新的缓存..)，有没有办法清除漫游器的缓存?

This is Network snapshot (may be useful) >> I see 302 (which I think there should be newer cache ..) so is there a way to clear the cache of the bot?

推荐答案

在顶部尝试以下操作

 Const JS_WAIT_CLICKABLE = _
    "var target = this, endtime = Date.now() + arguments[0];" & _
    "(function check_clickable() {" & _
    "  var r = target.getBoundingClientRect(), x = r.left+r.width/2, y = r.top+r.height/2;" & _
    "  for (var e = document.elementFromPoint(x , y); e; e = e.parentElement)" & _
    "    if (e === target){ callback(target); return; }" & _
    "  if (Date.now() > endtime) { callback(target); return; }" & _
    "  setTimeout(check_clickable, 60);" & _
    "})();"                                      'by @florentbr

然后

With .FindElementById("ctl00_ContentPlaceHolder1_LinkButton4")
    .ExecuteAsyncScript(JS_WAIT_CLICKABLE, 10000) _
    .Click
End With

您也可以尝试直接执行

You could also try to execute direct

.ExecuteScript "javascript:__doPostBack('ctl00$ContentPlaceHolder1$LinkButton4','');"

清除缓存并向后导航(由于按钮位于阴影根目录中，因此您需要使用/deep/组合器)

d.get "chrome://settings/clearBrowserData"
Dim button As Object
d.FindElementByCss("* /deep/ #clearBrowsingDataConfirm").Click
Set button = d.FindElementByCss("* /deep/ #clearBrowsingDataConfirm")

Const MAX_WAIT_SEC As Long = 15
Dim t As Date
t = Timer
Do
    DoEvents
    If Timer - t > MAX_WAIT_SEC Then Exit Do
Loop Until button Is Nothing

d.ExecuteScript "window.history.go(-2);"

或可能

d.GoBack
