Use JS to close the window of the JS pop -up layer

<script type = "text/javascript">

function toggle () {) {

theobj = document.GetelementByid ('Sunyanzi'). Style;

If (theObj.display == "None") theObj.display = "Block"; else theObj.display = "None";

}

</script>

<div ID = "SUNYANZI" style = "Display: None"> You see me appeared ~~~ </div>

<br />

<input type = "Button" onClight = "Toggle ()" Value = "Try to see ...?" />

Two methods: remove and hide

// Create your pop -up layer

var dvmsg = document.createElement ("div");

strhtml = "<div class = '####'> pop -up layer content </div>" "

Strhtml += "<div class = '####'> <input type = 'Button' value = 'Turn off' OnClick = 'Btnclick ()'> </DIV>"

dvmsg.innerhtml = strhtml;

document.body.appendchild (DVMSG);

// Close the button

btnclICK = Function () {{

document.body.removechild (DVMSG);

---------------------------

Or the pop -up layer is marked with a div ID

<div ID = "tanchu"> pop -up layer content </div>

in JS

function open () {

document.GetelementByid (tanchu) .style.display = "" "; // display

}

Function close () {) {

document.GetelementByid (tanchu) .style.display = "None"; // No display (the page was also loaded once when the page initialized)

}
