javascript - 验证文本区域中逗号分隔词的字符数

Question

我正在尝试验证在文本区域中输入的值，用户是否在逗号分隔值内输入了有效的十位数，例如

9876543210,98766543211,98766543212

如果用户输入的数字多于或少于 10 位，则必须提示错误。

到目前为止我已经尝试过类似的东西

$("#myMso").keyup(function(){
    var value = $(this).val().replace(" ", "");
    var word = value.split(",");

    var lengths = words.map(function(word) {
        if(lengths != 10){
            alert("Hey! some of the contact number you have entered is not valid");
        }
    });
 }); 

Answer 1

这样试试

   $("#myMso").keyup(function(){
        var value = $(this).val();
        var word = value.split(",");
        $.each(word,function (key,value) {
            if(value.length != 10){
                alert("Hey! some of the contact number you have entered is not valid");
            }

        });
     }); 

修改 on-change 事件:-

 $("#myMso").on('change',function(){
            var value = $(this).val();
            var word = value.split(",");
            $.each(word,function (key,value) {
                if(value.length != 10){
                    alert("Hey! some of the contact number you have entered is not valid");
                }

            });
         });
