仅在页面加载时执行Javascript，而不是PostBack（SharePoint） [英] Execute Javascript only on page load, not PostBack (SharePoint)

问题描述

我正在尝试在SharePoint网站上的自定义页面上执行页面加载上的一些JavaScript（它使用当前用户填充人员选择器）。问题是代码也在回发上执行，我不想要，因为它会重置对人员选择器的任何更改。

I'm trying to execute some JavaScript on page load on a custom page on a SharePoint site (it populates the people picker with the current user). The problem is that the code executes on postback too, which I don't want as it will reset any changes to the people picker.

我尝试过使用 if（！IsPostBack）无济于事。这一切都出错了，给出了

I've tried using if(!IsPostBack) to no avail. Everything errors out at that point, giving

SCRIPT5009：'IsPostBack'未定义。

SCRIPT5009: 'IsPostBack' is undefined.

我在网上找不到任何帮助。有任何想法吗？谢谢

I can't find anything online to help with this. Any ideas? Thanks

推荐答案

您可以创建这样的函数：

You can create a function like this:

function IsPostBack() {
    var ret = '<%= Page.IsPostBack%>' == 'True';
    return ret;
}
