Question

如何从我的代码页面后面调用这个jquery函数。我无法理解语法是什么。任何helo都会被大大贬低。它弹出一个窗口供用户注册。我想在用户在网站上查看5个页面后弹出页面。我想把这个计数保存在一个会话变量中。

Html页面

<ul>

<li><a href="#dialog" name="modal">Simple Window Modal</a></li>

</ul>
div id="dialog" class="window">

<a href="#"class="close">Close it</a>
<br /><br />
Register Now its quick and Easy.<br />
Rules: 

        1) Items with "*" are required fields to be filled out.

Jquery函数

<script>

$(document).ready(function () {

    //select all the a tag with name equal to modal
    $('a[name=modal]').click(function (e) {
        //Cancel the link behavior
        e.preventDefault();

        //Get the A tag
        var id = $(this).attr('href');

        //Get the screen height and width
        var maskHeight = $(document).height();
        var maskWidth = $(window).width();

        //Set heigth and width to mask to fill up the whole screen
        $('#mask').css({ 'width': maskWidth, 'height': maskHeight });

        //transition effect     
        $('#mask').fadeIn(1000);
        $('#mask').fadeTo("slow", 0.8);

        //Get the window height and width
        var winH = $(window).height();
        var winW = $(window).width();

        //Set the popup window to center
        $(id).css('top', winH / 2 - $(id).height() / 2);
        $(id).css('left', winW / 2 - $(id).width() / 2);

        //transition effect
        $(id).fadeIn(2000);

    });

    //if close button is clicked
    $('.window .close').click(function (e) {
        //Cancel the link behavior
        e.preventDefault();

        $('#mask').hide();
        $('.window').hide();
    });

    //if mask is clicked
    $('#mask').click(function () {
        $(this).hide();
        $('.window').hide();
    });

});

Answer 1

它不必在代码中，你可以将代码包装在ASPX文件的代码块中;

<% if( ( (int)Session["PageViews"] ) > 5 ) { %>
  <script type="text/javascript">
    $(document).ready(function() {
      // This code will only execute when PageViews > 5
    });
  </script>
<% } %>

这里我们刚刚在服务器端检查中包装了所有代码。如果检查返回false，则代码将不会呈现给页面。

Answer 2

以下是将脚本注册到Response：

的示例代码段

if(Session["_PageVisitCount"].ToString() == "5"){
    Page.ClientScript.RegisterStartupScript(
        this.GetType(),
        "scriptsKey",
        "yourScriptMethodToCall();",
        true
    );
}

在进一步检查代码之后，没有任何可以显式调用的客户端代码。你错过了任何脚本吗？

Answer 3

你不能从后面的代码中调用js脚本。但是，正如其他人所示，当响应被发送回客户端时，您可以注册一个脚本来调用jquery函数。
