判断填空字符长度

function countTextLength(inputText) {	var wordCount = 0.0;	inputText= inputText.replace('/<[^>]*>/g','');	for (var i = 0; i < inputText.length; i++) {		if (inputText.charCodeAt(i) >= 65 && inputText.charCodeAt(i) <= 90) { //大写字母			wordCount+=0.5;		} else {			var code = escape(inputText.charAt(i));			if ((code.length >= 4) && (code < '%uFF60' || code > '%uFF9F')) { //中文				wordCount++;			} else {				wordCount+=0.5;			}		}	}	return wordCount;} ;
