英文首字母全大写的js实现脚本_javascript技巧

完整代码：

<script language="JavaScript"> <!-- Begin function changeCase(frmObj) { var index; var tmpStr; var tmpChar; var preString; var postString; var strlen; tmpStr = frmObj.value.toLowerCase(); strLen = tmpStr.length; if (strLen > 0) { for (index = 0; index < strLen; index++) { if (index == 0) { tmpChar = tmpStr.substring(0,1).toUpperCase(); postString = tmpStr.substring(1,strLen); tmpStr = tmpChar + postString; } else { tmpChar = tmpStr.substring(index, index+1); if (tmpChar == " " && index < (strLen-1)) { tmpChar = tmpStr.substring(index+1, index+2).toUpperCase(); preString = tmpStr.substring(0, index+1); postString = tmpStr.substring(index+2,strLen); tmpStr = preString + tmpChar + postString; } } } } frmObj.value = tmpStr; } // End --> </script> <form name="form"> <input type="text" name="box" value="type in here!"> <input type="button" value="Convert" onclick="javascript:changeCase(this.form.box)"> </form>
