仅在加载时执行功能

Question

我怎样才能使它始终有效，而不是每次加载页面时都是如此？

$(function(){

    $('#test').click(function () {
        test();
    });

});

var calledonetime = false;

function test()
{
    if(calledonetime=== false)
    {
        calledonetime = true;
        $('html').css("overflow","hidden");
    }else
    {
        $('html').css("overflow","scroll");
   $('html').css("overflow-x","hidden");
    }

}

Answer 1

愿这项工作：

Dim receipes(4)
Dim receipe

receipes(0) = "chicken soup"  'Chicken Soup
receipes(1) = "turkey"        'Turkey
receipes(2) = "mash potatoes" 'Mash Potatoes
receipes(3) = "yams"          'Yams
receipes(4) = "stuffing"      'Stuffing

For Each receipe In receipes
  WScript.Echo receipe
Next

Answer 2

JS：

$( document ).ready(function() {
  $('#test').click(function () {
    $('body').toggleClass("sroll");
  });
});

CSS中的

body {
    overflow: scroll;
}

body.no-scroll {
    overflow: hidden;
}

修正了它：添加：calledonetime = false; to else

$(function(){

    $('#test').click(function () {
        test();
    });

});

var calledonetime = false;

function test()
{
    if(calledonetime=== false)
    {
        calledonetime = true;
        $('html').css("overflow","hidden");
    }else
    {
    $('html').css("overflow","scroll");
   $('html').css("overflow-x","hidden");
calledonetime = false;
    }

}
