在共享点中选择下拉选项时，需要 jquery 代码来禁用下拉菜单和人员选择器

Question

我正在使用 moss 2007。我创建了一个下拉列，其中包含 3 个选项。如果选择了选项 1 和选项 2，则应禁用下拉菜单和人员选择器，如果选择了选项 3，则应启用下拉菜单和人员选择器列。我提供了页面源代码，由于我是 jquery 的新手，有人可以帮我解决这个问题。

Answer 1

不确定如何禁用您的人员选择器（没有从您的 html 中看到/理解）。但这将处理下拉菜单。

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" ></script>
<script type="text/javascript">
    $(function(){
        $('select[title="Type of Notification"]').change(function(){
            if($(this).val() == "Option1" || $(this).val() == "Option2")
            {
                $('select').not(this).attr('disabled', 'disabled');
            }else if($(this).val() == "Option3"){
                $('select').not(this).removeAttr('disabled');
            }
        });
    });
</script>

Answer 2

PeopleEditor 相当复杂和烦人。您需要处理多个组件才能禁用它。在 IE 中有一个 contentEditable div 这是您可以输入的主要输入。您还可以处理带有onclick 的图像按钮。然后在非IE浏览器中我相信它使用textarea。

你需要做这样的事情（未经测试，你可能需要调整它）：

$("span[id$='_UserField']").find(":input").val("").attr("disabled",true); 

以上将清除和禁用控件使用的所有输入字段（包括textarea）。

然后你需要处理内容可编辑的div。我不确定您是否可以disable 它或者您是否需要像这样更改contentEditable 属性：

$("div[id$='_UserField_upLevelDiv']").text("").attr("contentEditable",false);

最后是图片。图像被包装在带有 onclick 的 a 标记中。我的建议是像这样隐藏它们：

$("span[id$='_UserField']").find("img").hide();

希望对您有所帮助。如果你能侥幸逃脱，那么隐藏整个事情会容易得多。

Answer 3

另一种选择是使用SPUtility.js（完全公开，我维护这个开源库）。它依赖于 Prototype.js，所以你可能不感兴趣，因为你使用的是 jQuery。

它支持隐藏和/或禁用许多不同的字段类型.. 包括人员选择器：

// make a people field read only
SPUtility.GetSPField('Assigned To').MakeReadOnly();
// hide the people field
SPUtility.GetSPField('Assigned To').Hide();
