如何判断一个字符串是全英文还是全中文的?

[bjhb2004]

如题,多谢!

[spring11]

var s='我的一个测试';
var ms=s.match(/[^\x00-\xff]/g);
alert(ms);

[spring11]

关键是中间那一句。判断是否有中文。

[vivianfdlpw]

var str = 'df2测试12fhfh';
if(str.search(/[0-9]+/)==(-1))
{
alert('不包含数字');
}
else
{
alert('包含数字');
}

[spring11]

楼上的跑题了。。。看清题目。。。是判断中英文混编。。不是数字

[vivianfdlpw]

var str = 'sd测试';
if(str.search(/[a-zA-Z]+/)==(-1))
{
alert('不包含英文'+str);
}
else
{
alert('包含英文'+str);
}

建议楼上的抛弃search用match试试嘛。。。做程序何必那么死板呢。。嘿嘿～～～

function isChinese(inputStr){
iLength = inputStr.length
for (i = 0; i < iLength; i++)
if (inputStr.charCodeAt(i) > 255){ //是否为汉字
alert("不能输入汉字！");
return true ;
}
return false ;
}

function checkOtherChar(str,errmsg) {
for(var loop_index=0; loop_index<str.length; loop_index++)
{
if(str.charAt(loop_index) == '~'
||str.charAt(loop_index) == '!'
||str.charAt(loop_index) == '@'
||str.charAt(loop_index) == '#'
||str.charAt(loop_index) == '$'

{
//alert("~,,,!,@,#,$,%,^,&,*,+,`,\',\",:,(,),[,],{,},<,>,|,\\ and / are illegal. Please re-input.");
alert(errmsg);
return false;
}
}//end of for(loop_index)
return true;
}
