当用户输入时，我的文本区域可以计算字符串/字符。这是我的jsfiddle .
我的问题是，当字符串/字符为 158 以上时，我想设置条件平均值，我想在 <div id="message">We will deduct 2 credit from your account</div> 内显示消息同样，当字符串/字符为 316 时，消息将更新并显示< div id="message">We will deduct 3 credit from your account</div>并继续..
示例:
158 *2
158 = We will deduct 2 credit from your account
316 = We will deduct 3 credit from your account
474 = We will deduct 4 credit from your account
632 = We will deduct 5 credit from your account
...
最佳答案
尝试一下
$('#myInput').keyup(function() {
$('#charCount').text(this.value.length);
var c = parseInt(this.value.length / 158);
if(c > 0)
$('#message').text('We will deduct '+c+' credit from your account');
});
