用JAVASCRIPT限制TextBox只能輸入數字或英文字...等

用JAVASCRIPT限制TextBox只能輸入數字或英文字...等 參考網址: http://bbs.flash2u.com.tw/FlashTopic51745_85_8_9.htm

文字框輸入限制：

<script> function regInput(obj, reg, inputStr) { var docSel = document.selection.createRange() if (docSel.parentElement().tagName != "INPUT") return false oSel = docSel.duplicate() oSel.text = "" var srcRange = obj.createTextRange() oSel.setEndPoint("StartToStart", srcRange) var str = oSel.text + inputStr + srcRange.text.substr(oSel.text.length) return reg.test(str) } </script>

小寫英文：<xmp style= "display:inline"> </xmp> <input onkeypress = "return regInput(this, /^[a-z]*$/, String.fromCharCode(event.keyCode))" onpaste = "return regInput(this, /^[a-z]*$/, window.clipboardData.getData('Text'))" ondrop = "return regInput(this, /^[a-z]*$/, event.dataTransfer.getData('Text'))" style="ime-modeisabled" ><br>

大寫英文：<xmp style= "display:inline"> </xmp> <input onkeypress = "return regInput(this, /^[A-Z]*$/, String.fromCharCode(event.keyCode))" onpaste = "return regInput(this, /^[A-Z]*$/, window.clipboardData.getData('Text'))" ondrop = "return regInput(this, /^[A-Z]*$/, event.dataTransfer.getData('Text'))" style="ime-modeisabled"> <br>

任意數字：<xmp style="display:inline"> </xmp> <input onkeypress = "return regInput(this, /^[0-9]*$/, String.fromCharCode(event.keyCode))" onpaste = "return regInput(this, /^[0-9]*$/, window.clipboardData.getData('Text'))" ondrop = "return regInput(this, /^[0-9]*$/, event.dataTransfer.getData('Text'))" style="ime-modeisabled" ><br>

限2位小數：<xmp style="display:inline"> </xmp> <input onkeypress = "return regInput(this, /^d*.?d{0,2}$/, String.fromCharCode(event.keyCode))" onpaste = "return regInput(this, /^d*.?d{0,2}$/, window.clipboardData.getData('Text'))" ondrop = "return regInput(this, /^d*.?d{0,2}$/, event.dataTransfer.getData('Text'))" style="ime-modeisabled" > 如: 123.12<br>

日　 期：<xmp style="display:inline"> </xmp> <input onkeypress = "return regInput(this, /^d{1,4}([-/](d{1,2}([-/](d{1,2})?)?)?)?$/, String.fromCharCode(event.keyCode))" onpaste = "return regInput(this, /^d{1,4}([-/](d{1,2}([-/](d{1,2})?)?)?)?$/, window.clipboardData.getData('Text'))" ondrop = "return regInput(this, /^d{1,4}([-/](d{1,2}([-/](d{1,2})?)?)?)?$/, event.dataTransfer.getData('Text'))" style="ime-modeisabled" > 如: 2002-9-29<br>

任意中文：<xmp style="display:inline"> </xmp> <input onkeypress = "return regInput(this, /^$/, String.fromCharCode(event.keyCode))" onpaste = "return regInput(this, /^[u4E00-u9FA5]*$/, window.clipboardData.getData('Text'))" ondrop = "return regInput(this, /^[u4E00-u9FA5]*$/, event.dataTransfer.getData('Text'))" ><br>

部分英文：<xmp style="display:inline"> </xmp> <input onkeypress = "return regInput(this, /^[a-e]*$/, String.fromCharCode(event.keyCode))" onpaste = "return regInput(this, /^[a-e]*$/, window.clipboardData.getData('Text'))" ondrop = "return regInput(this, /^[a-e]*$/, event.dataTransfer.getData('Text'))" style="ime-modeisabled" > 範圍: a,b,c,d,e<br>

部分中文：<xmp style="display:inline"> </xmp>

<script language=javascript> function checkChinese(oldLength, obj) { var oTR = window.document.selection.createRange() var reg = /[^一二三四五六七八九十]/g oTR.moveStart("character", -1*(obj.value.length-oldLength)) oTR.text = oTR.text.replace(reg, "") } </script> <input onkeypress="return false" onkeydown="setTimeout('checkChinese('+this.value.length+','+this.uniqueID+')', 1)" 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'))" > 範圍: 一二三四五六七八九十
