本文实例讲述了jquery比较简洁的软键盘特效实现方法。而且带有数字与字母切换功能,效果非常不错,分享给大家供大家参考。
用法简介:
jquery页面虚拟键盘设计带有数字与字母切换功能。
文件引用:
//给输入的密码框添加新值
function addValue(newValue)
{
CapsLockValue==0?$(".input_cur").val($(".shuru").val()+ newValue):$(".input_cur").val($(".shuru").val()+ newValue.toUpperCase())
}
//清空
function clearValue()
{
$(".input_cur").val("");
}
//实现BackSpace键的功能
function backspace()
{
var longnum=$(".input_cur").val().length;
var num ;
num=$(".input_cur").val().substr(0,longnum-1);
$(".input_cur").val(num);
}
function changePanl(oj){
$("#"+oj).siblings("div").hide();
$("#"+oj).show();
}
//设置是否大写的值
function setCapsLock(o)
{
if (CapsLockValue==0){
CapsLockValue=1;
$(o).val("转化小写");
$.each($(".i_button_zm"),function(b, c) {
$(c).val($(c).val().toUpperCase());
});
}else{
CapsLockValue=0;
$(o).val("转化大写");
$.each($(".i_button_zm"),function(b, c) {
$(c).val($(c).val().toLowerCase());
});
}
}
window.onload=function(){
// changePanl("zimu");
}

演示效果:
屏幕键盘在网络生活中很常见,比如使用网银或在线查询信用卡余额,在输入密码等敏感数据时,应该就会用到屏幕键盘。以防止被木马或恶意程序捕获盗取实际键盘上的操作。希望本文能够对大家有所帮助。 |
