回答1:

To show a tag use

$('#child').show();  // where child is the id of the element

and to hide ...

$('#child').hide();

alternatively, you can simply toggle it between hide/show as follows:

$('#child').toggle();

to attach these to an onclick event of a button ...

$(document).ready(function() {
    $('#buttonID').click(function() {
        $('#child').toggle();
    });
});

hope this helps

回答2:

The below code is for javascript

var Home= document.getElementById("home");

Home.style.display="none";//To hide the div
Home.style.display="";//To display the div

$(document).ready(function(){
