        console.log(arr);

推荐答案

首先.对于输入多行，您需要使用<textarea>

First. For input multiline you need to use <textarea>

然后用

("Yourtext").split("Your Seperator",limit_arraysize);

//example
alert(("Howdy! I'm Flowey the flower").split(" ",3)); 
//That mean you split with " " (1 blank space)

输出:

[
    "Howdy!"
    ,"I'm"
    ,"Flowey"
]

下面的一些例子

function myFunction() {
  var arr = [];
  var text = $("textarea").val();

  var submit = text.split("\n"); // USE TO split multiline
  for (var i = 0; i < submit.length; i++) {
    var temp = submit[i].split(",", 2);
    arr[i] = {
      value: temp[0],
      name: temp[1]
    };
  }

  console.log(arr);
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<textarea type="text" style="width: 400px;height:200px;" class="in">
25,ok
80,good
90,no</textarea>
<!--use TEXTAREA instead INPUT for multiline-->

<br>
<input type="button" value="submit" onclick="myFunction()" />
