  1.文本框输入限制
  实现限制输入大、小写英文,数字,浮点小数,日期,中文,部分英文,部分中文等众多功能。直接加入到html代码中即可使用。

小写英文:


onpaste = "return regInput(this, /^[a-z]*$/, window.clipboardData.getData('Text'))"

ondrop = "return regInput(this, /^[a-z]*$/, event.dataTransfer.getData('Text'))"

style="ime-mode:Disabled"

>

大写英文:


onpaste = "return regInput(this, /^[A-Z]*$/, window.clipboardData.getData('Text'))"

ondrop = "return regInput(this, /^[A-Z]*$/, event.dataTransfer.getData('Text'))"

style="ime-mode:Disabled">



任意数字:


onpaste = "return regInput(this, /^[0-9]*$/, window.clipboardData.getData('Text'))"

ondrop = "return regInput(this, /^[0-9]*$/, event.dataTransfer.getData('Text'))"

style="ime-mode:Disabled"

>

限2位小数:


onpaste = "return regInput(this, /^\d*\.?\d{0,2}$/, window.clipboardData.getData('Text'))"

ondrop = "return regInput(this, /^\d*\.?\d{0,2}$/, event.dataTransfer.getData('Text'))"

style="ime-mode:Disabled"

> 如: 123.12



日  期:


onpaste = "return regInput(this, /^\d{1,4}([-\/](\d{1,2}([-\/](\d{1,2})?)?)?)?$/,
window.clipboardData.getData('Text'))"

ondrop = "return regInput(this, /^\d{1,4}([-\/](\d{1,2}([-\/](\d{1,2})?)?)?)?$/,
event.dataTransfer.getData('Text'))"

style="ime-mode:Disabled"

> 如: 2002-9-29

任意中文:


onpaste = "return regInput(this, /^[\u4E00-\u9FA5]*$/, window.clipboardData.getData('Text'))"

ondrop = "return regInput(this, /^[\u4E00-\u9FA5]*$/, event.dataTransfer.getData('Text'))"

>

部分英文:


onpaste = "return regInput(this, /^[a-e]*$/, window.clipboardData.getData('Text'))"

ondrop = "return regInput(this, /^[a-e]*$/, event.dataTransfer.getData('Text'))"

style="ime-mode:Disabled"

> 范围: a,b,c,d,e

部分中文:



onpaste = "return regInput(this, /^[一二三四五六七八九十]*$/, window.clipboardData.getData('Text'))"

ondrop = "return regInput(this, /^[一二三四五六七八九十]*$/, event.dataTransfer.getData('Text'))"

> 范围: 一二三四五六七八九十



  2.不能展开右键,不能全选,不能复制的实现


onkeypress="window.event.returnValue=false"

onkeydown="window.event.returnValue=false"

onkeyup="window.event.returnValue=false"

ondragstart="window.event.returnValue=false"

onselectstart="event.returnValue=false">
...



 
  3.禁止页面正文内容被选取

onselectstart ="return false" onselect="document.selection.empty()"
oncopy="document.selection.empty()" onbeforecopy="return

false"onmouseup="document.selection.empty()">


  4.避免别人把网页放在框架中
