dart - 如何使用每个功能，从jquery到Dart Language？

Question

我在jquery中有一个函数，如下所示

function findMax(){
 $( ".elements" ).each(function( ) {
  if($(this).css('z-index')>max1)
  max1=$(this).css('z-index');
  max1=parseInt(max1);
 });
}

我必须用Dart语言实现此功能。使用.each函数和'this'函数时遇到的语法问题。

相当于jQuery:

$(".elements").each(function( ) {
  // do something with this being one of elements with a 'elements' class
  // you can access the current element with $(this)
});

在Dart中:

querySelectorAll('.elements').forEach((Element e) {
  // do something with e being one of elements with a 'elements' class
  // you can access the current element with e
});
