/*
How the Document node object is obtained:
*/
The first type is obtained by ID
function Documentdemo () {
var tablenode = document.getElementById ("tab_id");
TableNode.style.border = "5px solid #00ff00";
}
The second, through the Name property
function DocumentDemo2 () {
var inputnode = document.getelementsbyname ("txt");
alert (inputnode.length);
alert (Inputnode[0].value);
}
Third, by sign
function DocumentDemo3 () {
var tdnode = document.getElementsByTagName ("TD");
alert (tdnode.length);
for (var x = 0; x < tdnode.length;x++) {
alert (Tdnode[x].innertext);
}
}
