javascript - 对方法或属性访问的意外调用。微软客户关系管理

Question

我有以下 js 脚本，可在 ms crm 中的 FormLoad 事件上运行。

function showForm() {
    if (Xrm.Page.ui.getFormType() == 2) {
        Xrm.Page.ui.controls.get("pcrm_contactfield").setDisabled(true);
        Xrm.Page.ui.controls.get("pcrm_privatefield").setDisabled(true);
        return;
    }

    processField("contact", "pcrm_contactfield");
    processField("pcrm_userconnection", "pcrm_privatefield");
    var userName = '';
    var lblUser = parent.document.getElementById('lblUserName');
    if (lblUser != null)
        if (typeof lblUser.innerText != "undefined")
            userName = lblUser.innerText;
        else
            userName = lblUser.innerHTML;
    else
        userName = Xrm.Page.context.getUserName();

    if (!Xrm.Page.data.entity.getId()) {
        var userControl = Xrm.Page.getControl("pcrm_userid");
        if (userControl) {
            if (XrmServiceToolkit.Soap.IsCurrentUserRole("PCRM Connections Manager")) {
                userControl.setDisabled(false);
            } else {
                var userAttribute = Xrm.Page.getAttribute("pcrm_userid");
                var lookupValue = {
                    id: Xrm.Page.context.getUserId(),
                    entityType: "systemuser",
                    name: userName
                };
                userAttribute.setValue([lookupValue]);
                userAttribute.setSubmitMode("always");
            }
        }
    }
}

function processField(entityName, field) 
{
    SDK.Metadata.RetrieveEntity(SDK.Metadata.EntityFilters.Attributes, entityName, null, false,
    function (entityMetadata) {
        entityMetadata.Attributes.sort(function (a, b) {
            if (a.LogicalName < b.LogicalName)
                return -1;
            if (a.LogicalName > b.LogicalName)
                return 1;
            return 0;
        });
        applySelect(field, entityMetadata.Attributes);
    },
    function () {
    });
}

function applySelect(id, attributes) {
    if (parent.document.getElementById(id + "_container"))
        parent.document.getElementById(id + "_container").style.display = "none";
    else if (parent.document.getElementById(id)) {
        parent.document.getElementById(id).style.display = "none";
        parent.document.getElementById(id + "_d").style.display.paddingLeft = "23px";
    }

    var selectControl = "<select style='width: 100%' id ='" + id + "_select' onchange='onChange(this, \"" + id + "\")'><option></option>";
    var value = Xrm.Page.data.entity.attributes.get(id).getValue();

    for (var i = 0; i < attributes.length; i++) {
        if (attributes[i].IsPrimaryId || attributes[i].AttributeType == "Lookup" || attributes[i].DisplayName.LocalizedLabels.length == 0)
            continue;

        var logicalName = attributes[i].LogicalName;
        if (logicalName == "createdon" || logicalName == "modifiedon" || logicalName == "importsequencenumber" ||
            logicalName == "overriddencreatedon" || logicalName == "ownerid" || logicalName == "statecode" || logicalName == "statuscode" ||
            logicalName == "timezoneruleversionnumber" || logicalName == "utcconversiontimezonecode")
            continue;

        selectControl += "<option" + (value == logicalName ? " selected" : "") + " value='" + logicalName + "'>" + logicalName + " (" + attributes[i].DisplayName.LocalizedLabels[0].Label + ")</option>";
    }
    selectControl += "</select>";

    parent.document.getElementById(id + "_d").innerHTML += selectControl;
}

parent.onChange = function (control, field) {
    Xrm.Page.data.entity.attributes.get(field).setValue(control.value);
}

现在我解释一下他在做什么。我有表单，这个 js 代码动态创建两个 <select>元素。此代码还将元素与一些数据绑定(bind)。此功能在 applySelect 方法中起作用。
它工作没有错误。我可以选择一些选项，单击“保存”并创建新记录。这是异步工作的。
但是，当调用另一个重定向到另一个页面或刷新当前页面的事件时，就会出现 js 错误。这仅在 IE 中重现，我不认为这是 MS CRM 中的功能或错误。来自 CRM 的消息如下所示:

我做错了什么？如果可能的话如何解决？

Answer 1

您的代码正在篡改表单的 DOM，这是不受支持的，应该避免，因为它可能会导致表单以不可预测的方式运行，并且在使用 Service Pack 或新版本更新 CRM 时也可能会中断。

当您的表单上需要一段自定义 HTML 时，请使用 HTML Web 资源。
