Javascript client traverses the control and obtains the sample code of the parent container object

1. traverse all the controls
Function findControlAll ()
{
Var inputs = document. getElementsByTagName ("input ");
For (j = 0; j <inputs. length; j ++)
If (inputs [j]. type = "text") // you can find all the controls whose types are text, or set them to the control type you want to traverse.
{
Inputs [j]. value = ""; // clear the content of the text box.
}
}
2. traverse the controls in the specified container
Function findControl ()
{
// The following table 1 refers to traversing the control in the table
Var inputs = document. getElementById ("table1"). getElementsByTagName ("input ");
For (var I = 0; I <inputs. length; I ++)
{
If (inputs [I]. type = "text") // like the above, the type and operation of the control can be set as needed
{
Inputs [I]. value = "";
}
}
}

Get parent container object
Copy codeThe Code is as follows:
<Div>
<Input type = "button" value = "Get parent container object" onclick = "CheckBoxAll (this)"/>
</Div>

Function CheckBoxAll (e ){
// ParentNode is used to obtain the upper-level attributes.
Var obj = e. parentNode. getElementsByTagName ("*");}
