javascript - 如何隐藏/显示基于其他选项集的选项集 CRM Dynamics

Question

一个选项集定义了具有正确选项集的类别。然后第二个字段仅显示相关选项。但是，当我逐步执行它时，我一直在循环。我创建了一个包含所有正确值的数组并调用了它们，但我一直收到错误消息:

TypeError: Cannot read property 'toString' of undefined at Mscrm.TurboForm.Control.View.PicklistEditElement.addOption (https://ugcrmdev.crm9.dynamics.com/_static/form/formcontrols.js?ver=1659449427:24513:38)"

我不知道我做错了什么。

Answer 1

选择列表选项是一个键值对。应该像下面一样添加为一个选项:

(可能你可能需要保留多维数组来存储你正确的值)

var sheriff = { value : 100000000 , text : "sheriff123" };

var picklist = Xrm.Page.getControl("new_subjectmatter");
var options = picklist.getOptions();

function resetOptionSet()
{   
    for(var i = 0; i < options.length; i++){
        Xrm.Page.getControl("new_subjectmatter").removeOption(options[i].value);
    }
}

function showOptionSet(optionArray){
    for(var i = 0; i< optionArray.length; i++){
        Xrm.Page.getControl("new_subjectmatter").addOption(optionArray[i]);
    }   
}

另外，请考虑 resetOptionSet() 方法中的上述更改，以包含动态选项列表而不是硬编码。

Another approach如果您想尝试，这是一个很好的选择，使用依赖选项集的配置实体会让生活变得更轻松。
