WebBrowser控件使用问题
我通过 HtmlElement trHtml = htmlDoc.All[ "IncrProdTab "] 从 WebBrowser 里面获取以下代码段,现在我想在以下代码段里添加内容,并WebBrowser里显示最新的内容,但是我通过trHtml.InnerHtml=新内容却出现异常,请问我该怎么办呢?
<table id= "IncrProdTab ">
<TBODY>
<TR id=IncrProdRow_0>
<TD>
<INPUT title= " " value=A5 name=incrProd.prodClassCode>
<INPUT title= " " value=呼叫转移 name=incrProd.prodClassName>
</TD>
</TR>
<TR id=IncrProdRow_1>
<TD>
<INPUT title= " " value=A8 name=incrProd.prodClassCode>
<INPUT title= " " value=呼出限制 name=incrProd.prodClassName>
</TD>
</TR>
★★★我要在这里添加新的内容。
</TBODY>
</table>
★★★这是要添加的内容:
<tr id= "IncrProdRow_2 ">
<td>
<input type= "text " name= "incrProd.prodClassCode " value= "B8 ">
<input type= "text " name= "incrProd.prodClassName " value= "来电显示 ">
</td>
</tr>
------解决方案--------------------//参考如下代码:
//项目中添加Micrsoft.mshtml引用
using mshtml;
private void button1_Click(object sender, EventArgs e)
{
HtmlDocument htmlDoc = webBrowser1.Document;
HTMLTable htmlTable = htmlDoc.All[ "IncrProdTab "].DomElement as HTMLTable;
HTMLTableRow htmlRow = htmlTable.insertRow(htmlTable.rows.length) as HTMLTableRow;
htmlRow.id = "id=IncrProdRow_2 ";
HTMLTableCell htmlCell = htmlRow.insertCell(0) as HTMLTableCell;
htmlCell.innerHTML =
@ " <td> " +
@ " <input type= " "text " " name= " "incrProd.prodClassCode " " value= " "B8 " "> " +
@ " <input type= " "text " " name= " "incrProd.prodClassName " " value= " "来电显示 " "> " +
@ " </td> ";
}
------解决方案--------------------使用HTMLTable,将htmlDoc.All[ "IncrProdTab "]转化成HTMLTable,然后使用新建一行,并插入你的内容即可。
