英文首字母全大写的js实现脚本_javascript技巧



完整代码：
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>
[Ctrl+A 全选 注:如需引入外部Js需刷新才能执行]
脚本说明:
第一步:把如下代码加入区域中

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 -->
