Question

如果我有一些内部使用ng-repeat的模板并将其包含在ng-include中，实际会发生什么？将包含已完成ng-repeat的模板，或未完成ng-repeat的模板（以及包括ng-repeat之后的模板）？

Answer 1

ngInclude指令首先将从模板返回的html附加到html DOM。然后它编译它的内容。

正如您在ngInclude的源代码中看到的那样

// This directive is called during the $transclude call of the first `ngInclude` directive.
// It will replace and compile the content of the element with the loaded template.
// We need this directive so that the element content is already filled when
// the link function of another directive on the same element as ngInclude
// is called.
var ngIncludeFillContentDirective = ['$compile',
  function($compile) {
    return {
      restrict: 'ECA',
      priority: -400,
      require: 'ngInclude',
      link: function(scope, $element, $attr, ctrl) {
        if (/SVG/.test($element[0].toString())) {
          // WebKit: https://bugs.webkit.org/show_bug.cgi?id=135698 --- SVG elements do not
          // support innerHTML, so detect this here and try to generate the contents
          // specially.
          $element.empty();
          $compile(jqLiteBuildFragment(ctrl.template, document).childNodes)(scope,
              function namespaceAdaptedClone(clone) {
            $element.append(clone);
          }, {futureParentElement: $element});
          return;
        }

        $element.html(ctrl.template);
        $compile($element.contents())(scope);
      }
    };
  }];

查看行

    $element.html(ctrl.template);
    $compile($element.contents())(scope);

这意味着它首先将它添加到DOM中，然后进行编译。

在底线，您将其描述为

它是一个没有完成ng-repeat的模板（并且在包含ng-repeat之后完成）

首先，AngularJS中的ng-include或ng-repeat是什么？
