[英]VB.NET / C#.Net MSHTML: Unable to get “name” attribute from Outerhtml after using “setAttribute('name',value)” for certain elements
我正在開發一種所見即所得的應用程序,專門用於與公司現有工具進行自定義集成的公司用途。
當嘗試通過使用“ .OuterHtml”(尤其是INPUT標簽元素)獲取html字符串時,無法從某些元素中獲取“ name”屬性。
`Dim inElem as windows.forms.htmlElement = hdoc.CreateElement("INPUT")`
`inElem.Id = "txt01"`
`inElem.setAttribute("name", inElem.Id)`
`inElem.setAttribute("type", "text")`
`inElem.setAttribute("placeholder","text here....")`
'' append the created element to html body
`hdoc.Body.AppendChild(inElem)`
--> Getting html string:
** hdoc.body.getElementById("txt01").OuterHtml => "<input id=txt01 placeholder='text here....'></input>"
--> What I really want is:
** hdoc.body.getElementById("txt01").OuterHtml => "<input id=txt01 placeholder='text here....' type='text' name='txt01'></input>"
是的,不僅缺少名稱屬性,還有一些其他屬性。 (例如TYPE)有人可以幫助我嗎?
For Each inputEle As Windows.Forms.HtmlElement In hdoc.Body.GetElementsByTagName("input")
CType(inputEle.DomElement, mshtml.IHTMLInputElement).name = inputEle.Id
Next
**失敗** :(
Use HTML Agility Pack:
----------------------
Dim inputEle3 As HtmlAgilityPack.HtmlNode = new_wb.CreateElement("input")
inputEle3.Attributes.Add("id", "txt01")
inputEle3.Attributes.Add("name", inputEle3.Id)
inputEle3.Attributes.Add("type", "text")
inputEle3.Attributes.Add("placeholder", "text here ....")
RESULT:
-------
inputEle3.OuterHtml => <input id="txt01" name="txt01" type="text" placeholder="text here ...." >
只要我使用HtmlAgilityPack.dll :(微軟mshtml很爛!:(
這對我有用。 原諒我使用dynamic
數據類型,由於某種原因我在Visual Studio上沒有mshtml
庫。
private void Form1_Load(object sender, EventArgs e)
{
this.webBrowser1.Navigate("about:blank");
this.webBrowser1.Document.Write("<INPUT id='hell' class='blah' placeholder='text here' name='hell' type='text'></INPUT>");
dynamic htmldoc = webBrowser1.Document.DomDocument as dynamic;
dynamic node = htmldoc.getElementById("hell") as dynamic;
string x = node.OuterHtml; //gets name but not type
string s = node.GetAttribute["type"]; //gets type
string name = node.GetAttribute["name"]; //gets name
}
所以說的OuterHtml沒有獲得屬性,但是在調用GetAttribute方法時它確實起作用。 希望這會有所幫助。
