Use the js implementation to close the window of js pop up layer

< The script type = "text/javascript" >
The function toggle () {
  TheObj = document. GetElementById (' Sunyanzi). Style;
  If (  Theobj. display == "none") theobj. display = "block"; The else theObj. The display = "none";
}
< / script>
< Div id = "Sunyanzi" style = "display: none" > There I am. / div>
< Br / >
< Input type="button" onclick="toggle()" value=" ?" / >

Two methods: remove and hide

// create your pop-up layer    
      Var dvMsg = document. The createElement method (" div ");  
      StrHtml =   "< Div class = '# # # #' > Pop-up layer content < / div>"
      StrHtml + = "< Div class = '# # # #' > < Input type='button' value=' close 'onclick='btnclick()'> < / div>"
      DvMsg. InnerHTML = strHtml;      
      Document. The body. The appendChild (dvMsg);
// close button        
Btnclick = function () {                                           
      Document. Body. RemoveChild (dvMsg);

-------------------------
Or the pop-up layer is marked with div id

< Div id = "tanchu" > Pop-up layer content < / div>

In js
The function open () {
Document. The getElementById (tanchu). Style. The display = "";   / / show
}
The function close () {
Document. The getElementById (tanchu). Style. The display = "none";   // not displayed (same load when page is initialized)
}
