Javascript 取消角度视图中的注释并更改视图

当我点击编辑按钮时，如果点击取消按钮返回，视图将被ng更改

    <div class="timeline-body">
                <div marked="cmnt.content" class="markdown" ng-if = "editPostComment != $index "  ></div>

                <!--Edit comment-->
                  <div class="commentBox" ng-if = "editPostComment == $index "  >
                    <textarea 
                    rows="10" > {{cmnt.content}}</textarea>
                    <div class="hints">
                      <span class="boldtext">**Bold**</span>
                      <span class="italictext">_itlaics_</span>
                      <span class="striktext">~~strike~~</span>
                      <span class="codetext">'code'</span>
                      <span class="codetext">'''preformatted'''</span>
                      <span class="quotetext">>quote</span>
                    </div>
                    <div id="comment-btns">
                      <button class="btn btn-primary pull-left" ng-class="{'loading': commentig}" ng-disabled="commentig" ng-click="cancel()">Submit</button>
                      <button class="btn btn-primary pull-left cancel-edit" ng-class="{'loading': commentig}" ng-disabled="commentig" ng-click = "cancelEdit()">Cancel</button>
                    </div>
                </div>
              </div>

{{cmnt.content}

取消

如果您的路线在单击“编辑注释”时发生了更改，您可以像在javascript中一样进行更改。试试这个

$scope.cancel = function(){
    $window.history.back();
}

但如果它仅取决于nf if条件，则可以将editPostComment的值设置为不同于$index，如下所示

$scope.cancel = function(editPostComment){
    editPostComment = null;
}

然后将“取消”按钮更改为

<button class="btn btn-primary pull-left" ng-class="{'loading': commentig}" ng-disabled="commentig" ng-click="cancel(editPostComment)">Submit</button>

提交

不，我不更改路线，当用户单击“取消”按钮时，我需要创建视图。当ng if=“editposcomment！=$index”时，会发生更改，但这不会发生，我只想在视图之间进行更改
