下面的代码将数字转换为单词。但问题是输入值是否具有某些值示例1.它仍然显示＆＃34;这里数字打印＆＃34;。 改变其变化的价值。如果默认情况下它有价值，则会以字格式显示。

<script type="text/javascript">
    var th = ['', ' thousand', ' million', ' billion', ' trillion', ' quadrillion', ' quintillion'];
    var dg = ['zero', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine'];
    var tn = ['ten', 'eleven', 'twelve', 'thirteen', 'fourteen', 'fifteen', 'sixteen', 'seventeen', 'eighteen', 'nineteen'];
    var tw = ['twenty', 'thirty', 'forty', 'fifty', 'sixty', 'seventy', 'eighty', 'ninety'];

    function update(){
        var numString =   document.getElementById('number').value;
        if (numString == '0') {
            document.getElementById('container').innerHTML = 'Zero';
            return;
        }
        if (numString == 0) {
            document.getElementById('container').innerHTML = 'messeg tell to enter numbers';
            return;
        }

        var output = toWords(numString);
        //print the output
        document.getElementById('container').innerHTML = output;
    }

    function toWords(s) {
        s = s.toString();
        s = s.replace(/[\, ]/g, '');
        if (s != parseFloat(s)) return 'not a number';
        var x = s.indexOf('.');
        if (x == -1) x = s.length;
        if (x > 15) return 'too big';
        var n = s.split('');
        var str = '';
        var sk = 0;
        for (var i = 0; i < x; i++) {

因此 var numString = document.getElementById('number').value; typeof numString //string 和numString == '0'是相同的。

您应该使用numString == 0或'numString === '0'代替
