Answer 1

在OnClientClick中返回false，即 -

OnClientClick="(document.getElementById('hdnSortOrder')).value='views'; return false;"

请注意，这意味着该按钮永远不会发回。

Answer 2

如果您从客户端点击功能返回false，则不会发生回发。

像

swipeRefreshLayout = (SwipeRefreshLayout)findViewById(R.id.buddy_requests_swipe_layout);
    swipeRefreshLayout.setColorSchemeResources(R.color.lb_green, R.color.lb_orange, R.color.lb_purple);
    swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            VolleyBuddies.makeGetBuddyRequestsAPICall(BuddyRequestsActivity.this, BuddyRequestsActivity.this);
        }
    });
    FrameLayout noRequestsLayout = (FrameLayout)findViewById(R.id.empty_view_requests);
    ListView requestsListView = (ListView)findViewById(R.id.buddy_requests_listview);
    requestListAdapter = new BuddyRequestsActivityListAdapter(this, this);
    requestsListView.setAdapter(requestListAdapter);
    requestsListView.setEmptyView(noRequestsLayout);

和脚本块是

 <asp:button runat="server" id="btn" OnClientClick="return myFunc();"/>

Answer 3

请使用：

 <asp:button runat="server" id="btn" OnClientClick="myFunc(); return false;"/>

然后：

<script>

 function myFunc(){

    //Do your javascript code here

  }

</script>

Answer 4

如果你想避免从按钮控制回发，只需从你的函数返回false。

<asp:button runat="server" id="btnTest" OnClientClick="anyFunction() return false;"/>
