使用excel VBA点击网站的按钮 [英] 'click' a website's button with excel VBA

问题描述

我有一个我正在写的脚本，我可以通过宏在网站上执行一个表单。我可以打开互联网浏览器，并正确传递所有的变量，但是当它提交的时候，我有点迷失了。

这是网站上的元素我想点击 - 它是一个标题为购买的按钮

 < input type =submitname =submit值= 购买 > 
  

我有两个问题：

1 ）我不知道如何正确地引用这个在vba
2）它旁边有一个按钮，将执行一个卖（完全相反的我想做的），其元素是：

 < input type =submitname =submitvalue =Sell>有没有人知道适当的代码来点击购买按钮？
 
 

这是我的代码到目前为止：

  Dim IE As Object 
 Set IE = New InternetExplorer 
 IE.Visible = True 
 IE.Navigatesomewebsite.com
 
尽管IE.Busy：DoEvents：Loop 
尽管IE.ReadyState< > 4：DoEvents：Loop 
 IE.Document.All（resourceoption）。Value =item
 IE.Document.All（amount）。Value = 1 
 IE.Document .All（priceper）。值= 99 
 Do While IE.Busy：DoEvents：Loop 
 Do While IE.ReadyState<> 4：DoEvents：Loop 
  

解决方案

 与IE.document 
 
设置elems = .getElementsByTagName（input）
对于每个e在elems 
 
如果（e.getAttribute（value ）=Buy）然后
 e.Click 
退出
结束如果
 
下一步e 
 
结束
  

上述代码段执行所需的任务

I have a script I am writing where I can execute a form on a website through a macro. I am able to open up internet explorer and pass all the variables correctly however when it comes time to submit, I am a bit lost.

this is the element on the website i want to click - it is a button titled "buy"

<input type="submit" name="submit" value="Buy">

I have two problems:

1) i don't know how to properly reference this within vba 2) there is a button right next to it that will perform a sell (the exact opposite of what i want to do) and the element for that is:

<input type="submit" name="submit" value="Sell">

Does anyone know appropriate code to hit the 'buy' button?

here is my code thus far:

Dim IE As Object
Set IE = New InternetExplorer
IE.Visible = True
IE.Navigate "somewebsite.com"

Do While IE.Busy: DoEvents: Loop
Do While IE.ReadyState <> 4: DoEvents: Loop
IE.Document.All("resourceoption").Value = "item"
IE.Document.All("amount").Value = 1
IE.Document.All("priceper").Value = 99
Do While IE.Busy: DoEvents: Loop
Do While IE.ReadyState <> 4: DoEvents: Loop

解决方案

With IE.document

    Set elems = .getElementsByTagName("input")
    For Each e In elems

        If (e.getAttribute("value") = "Buy") Then
            e.Click
            Exit For
        End If

    Next e

End With

the above snippet performs the task needed
