利用jquery实现禁用浏览器放大缩小
// chrome 浏览器直接加上下面这个样式就行了，但是ff不识别
$('body').css('zoom', 'reset');
$(document).keydown(function (event) {
//event.metaKey mac的command键
if ((event.ctrlKey === true || event.metaKey === true)&& (event.which === 61 || event.which === 107 || event.which === 173 || event.which === 109 || event.which === 187 || event.which === 189)){
event.preventDefault(); //阻止默认事件
}
});
//绑定鼠标滚轮
$(window).bind('mousewheel DOMMouseScroll', function (event) {
if (event.ctrlKey === true || event.metaKey) {
event.preventDefault();
}
});
