帮助向数组添加值

  • 772

无法为数组添加值，我做错了什么？

    var sd = $('#SD').val();
    var fi = $('#FI').val();
    var copa = $('#COPA').val();
    var mm = $('#MM').val();
    var sm = $('#SM').val();
    var cc = $('#CC').val();
    
    var autoArray = [];
    for (i = 0; i < autoArray; i++){
   autoArray.push(sd,fi,copa,mm,sm,cc);
}
console.log (autoArray);

  1. var autoArray = [
    $('#SD').val(),
    $('#FI').val(),
    $('#COPA').val(),
    $('#MM').val(),
    $('#SM').val(),
    $('#CC').val(),
]

    循环在那里没用：

        var sd = $('#SD').val();
    var fi = $('#FI').val();
    var copa = $('#COPA').val();
    var mm = $('#MM').val();
    var sm = $('#SM').val();
    var cc = $('#CC').val();

    var autoArray = [];
    autoArray.push(sd,fi,copa,mm,sm,cc);
    console.log (autoArray);

  3. 在这种数据包含中，您根本不需要循环。

        var sd = "10";
    var fi = "10";
    var copa = "10";
    var mm = "10";
    var sm = "10";
    var cc = "10";
    
    var autoArray = [sd,fi,copa,mm,sm,cc];
console.log (autoArray);

  4.  var vars = ["sd", "fi", "copa", "mm", "sm", "cc"];
 var autoArray = [];
 $.each(vars, function(key, val) {
  window[val] = $('#' + val.toUpperCase()).val();
  autoArray.push(window[val]);
 });
 console.log(autoArray);
