Question

我试图根据逗号分隔的分隔符拆分列表数组值。然后将其放入具有5个逗号分隔值的数组中。然后我再次在逗号分隔值上分隔每个数组并将它们分配给文本框。但我收到以下错误。请帮忙。

错误：对象不支持此属性或方法。

         list = list.slice(1,-1);                 // remove the enclosing []
         var allValues = list.split(/\s*,\s*/);   // split on comma with optional whitespace
         var a = [];
         var counter=0;
         for ( var i = 0 ; i < allValues.length ; i += 5 ) {
             a.push( allValues.slice( i, i+5 ) );

             for (var k = 0 ; k < a.length ; k++ ) {
                foo = a[i].split(",");

Answer 1

这里有一个问题：

      for (var k = 0; k < a.length; k++) {
            foo = a[i].split(",");

你的意思是

      for (var k = 0; k < a.length; k++) {
            foo = a[k].split(",");
                    ^ THIS

Answer 2

这是你的代码中的错误/错误：从（foo = a [i] .split（“，”）;）更改为foo = a [k]; 我让你成了小提琴：http://jsfiddle.net/Qtsqp/

  for (var i = 0; i < allValues.length; i+=5) {
      a.push( allValues.slice(i, i+5) );

      for (var k = 0; k < a.length; k++) {

            foo = a[k];
            for (var j = 0; j < foo.length; j++) {
                document.getElementById('name' + counter).value = foo[j];
                counter++;
            }
        }
  }
