Question

我在jQuery数据表中添加了下拉选项。

table.columns().every(function() {
    var column = this;
    var select = $('<select><option value=""></option></select>')
      .appendTo($(column.footer()).empty())
      .on('change', function() {
        var val = $.fn.dataTable.util.escapeRegex(
          $(this).val()
        );
        column
          .search(val ? '^' + val + '$' : '', true, false)
          .draw();
      });
    column.data().unique().sort().each(function(value, j) {
      select.append('<option value="' + value + '">' + value + '</option>')
    });
  });

当我打开下拉列表时，值被排序为String而不是整数。例如，这里的下拉列表给出了选择

[1,10,11,2,...] && [Item 1,Item 10,Item 11,...]

我想要回答

[1,2,3,4,..10,11..] && [Item 1,Item 2,Item 3,...]

您可以使用Sorting plugins

执行此操作

像这样修改你的代码：

let label = UILabel()
label.frame = CGRect(x: 120, y: 100, width: 200, height: 30)
let first = "first"
let second = "second"
let third = "third"
let stringValue = "\(first)\(second)\(third)"  // or direct assign single string value like "firstsecondthird"

let attributedString: NSMutableAttributedString = NSMutableAttributedString(string: stringValue)
attributedString.setColorForText(textToFind: first, withColor: UIColor.red)   // use variable for string "first"
attributedString.setColorForText(textToFind: "second", withColor: UIColor.green) // or direct string like this "second"
attributedString.setColorForText(textToFind: third, withColor: UIColor.blue)
label.font = UIFont.systemFont(ofSize: 26)
label.attributedText = attributedString
self.view.addSubview(label)
