本文介绍了Excel VBA回答Internet Explorer 11下载提示,在Windows 10中?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 我正在尝试使用Excel从 http://www.nasdaqomxnordic.com 自动下载.csv文件2010 VBA和Internet Explorer。 如何使用保存自动回复下载提示? 在我下载部分之前,VBA代码需要点击这个网页HTML代码的按钮: < div class =button showHistory floatRight> Visa historik< / div> 我正在使用这个VBA代码: 设置anchorElement = Document.getElementsByClassName(button showHistory floatRight)。Item(Index:= 1) anchorElement.Click / pre> 当我执行代码时,这可以工作,但是当我运行它时,我会收到一条错误消息在 anchorElement.Click 未指定对象变量或With-block变量。 任何有关1或2的建议?解决方案 XMLHttpRequest而不是IE自动化。在下面的示例中,共享ISIN被指定(用于AAK的SE0001493776),第一个请求返回共享ID(SSE36273),第二个请求通过id检索历史数据,然后在记事本中显示为文本,并保存为csv文件。 Sub Test() Dim dToDate,dFromDate,aDataBinary,sShareISIN,sShareId dToDate = Date'当天 dFromDate = DateAdd(yyyy,-1,dToDate)一年前 sShareISIN =SE0001493776'为AAK sShareId = GetId(sShareISIN)'SSE36273 aDataBinary = GetHistoryData (sShareId,dFromDate,dToDate) ShowInNotepad BytesToText(aDataBinary,us-ascii) SaveBytesToFile aDataBinary,C:\Test\HistoricData& sShareId& .csv End Sub 函数GetId(sName) Dim oJson 使用CreateObject(MSXML2.XMLHTTP)。打开GET ,http://www.nasdaqomxnordic.com/webproxy/DataFeedProxy.aspx?SubSystem=Prices&Action=Search&InstrumentISIN=& EncodeUriComponent(sName)& & json = 1,False .Send 设置oJson = GetJsonDict(.ResponseText)结束 GetId = oJson(inst)(@ id ) CreateObjectx86,True'关闭mshta主机窗口结束函数 函数EncodeUriComponent(strText)静态objHtmlfile作为对象如果objHtmlfile是设置objHtmlfile = CreateObject(htmlfile) objHtmlfile.parentWindow.execScript函数encode(s){return encodeURIComponent(s)},jscript End If EncodeUriComponent = objHtmlfile.parentWindow.encode(strText)结束函数 函数GetJsonDict(JsonString)使用CreateObjectx86(ScriptControl)'通过x86 mshta主机创建ActiveX,对于64位办公兼容性 .Language =JScript .ExecuteStatement函数gettype(sample){return {} .toString.call(sample).slice(8,-1)} .ExecuteStatement函数evaljson(json,er){t ry {var sample = eval('('+ json +')');

How to automate answering the download prompt with Save?Before I get to the download part the VBA code needs to click on a button with this web html code:<div class="button showHistory floatRight">Visa historik</div>I am using this VBA code: Set anchorElement = Document.getElementsByClassName("button showHistory floatRight").Item(Index:=1)anchorElement.ClickThis works when I step through the code but when I run it I get an error message on the line anchorElement.Click: Object variable or With-block variable is not specified.Any suggestions on 1 or 2? 解决方案 Consider downloading historic data for shares via XMLHttpRequest instead of IE automation. In the example below share ISIN is specified (SE0001493776 for AAK), first request returns share id (SSE36273), and second request retrieves historic data by id, then shows it in notepad as text, and saves as csv file.Sub Test() Dim dToDate, dFromDate, aDataBinary, sShareISIN, sShareId dToDate = Date ' current day dFromDate = DateAdd("yyyy", -1, dToDate) ' one year ago sShareISIN = "SE0001493776" ' for AAK sShareId = GetId(sShareISIN) ' SSE36273 aDataBinary = GetHistoryData(sShareId, dFromDate, dToDate) ShowInNotepad BytesToText(aDataBinary, "us-ascii") SaveBytesToFile aDataBinary, "C:\Test\HistoricData" & sShareId & ".csv"End SubFunction GetId(sName) Dim oJson With CreateObject("MSXML2.XMLHTTP") .Open "GET", "http://www.nasdaqomxnordic.com/webproxy/DataFeedProxy.aspx?SubSystem=Prices&Action=Search&InstrumentISIN=" & EncodeUriComponent(sName) & "&json=1", False .Send Set oJson = GetJsonDict(.ResponseText) End With GetId = oJson("inst")("@id") CreateObjectx86 , True ' close mshta host window at the endEnd FunctionFunction EncodeUriComponent(strText) Static objHtmlfile As Object If objHtmlfile Is Nothing Then Set objHtmlfile = CreateObject("htmlfile") objHtmlfile.parentWindow.execScript "function encode(s) {return encodeURIComponent(s)}", "jscript" End If EncodeUriComponent = objHtmlfile.parentWindow.encode(strText)End FunctionFunction GetJsonDict(JsonString) With CreateObjectx86("ScriptControl") ' create ActiveX via x86 mshta host, for 64-bit office compatibility .Language = "JScript" .ExecuteStatement "function gettype(sample) {return {}.toString.call(sample).slice(8, -1)}" .ExecuteStatement "function evaljson(json, er) {try {var sample = eval('(' + json + ')');

Let's suppose you are parsing web server response JSON, like JsonString = "{a:(function(){(new ActiveXObject('Scripting.FileSystemObject')).CreateTextFile('C:\\Test.txt')})()}". After evaluating it you'll find new created file C:\Test.txt. So JSON parsing with ScriptControl ActiveX is not a good idea.
