Dynamics CRM 365 - 无法访问HTML Web资源中的Xrm.Page.entity
[英]Dynamics CRM 365 - Cannot access Xrm.Page.entity in HTML web ressource
问题描述
I've added an html resource in my contact form which contains only an small image in order to place it just beside a contact field. 
我在我的联系表单中添加了一个html资源，其中只包含一个小图片，以便将它放在联系人字段旁边。 When the user clicks on it, it fires up a javascript function in which I want to get the value of a specific field of the form. 当用户点击它时，它会启动一个javascript函数，我想在其中获取表单特定字段的值。 The field is an attribute of the contact entity. 该字段是联系实体的属性。 Here is the HTML web ressource: 这是HTML Web资源：
<html>
<head>
<style type="text/css">
body
{
margin: 0;
padding: 0;
}
</style>
<script type="text/javascript">
function call() {
var phoneNumber = window.parent.Xrm.Page.getAttribute("mobilephone").getValue();
}
</script>
<meta>
</head>
<body style="word-wrap: break-word;">
<img onmouseover="this.style.cursor='pointer';" src="/webresources/new_/image/image.png" onclick="call()">
</body>
</html>
I have tried also to get data as follows: 我也尝试过获取如下数据：
window.parent.Xrm.Page.data.entity.attributes.get("telephone1").getValue()
But it doesn't work either: cannot read entity of null 但它也不起作用： 无法读取null的实体
The problem is that the getAttribut returns null despite the field of the entity that I want to get. 问题是getAttribut返回null，尽管我想要的实体字段。 It's always undefined Someone has an idea ? 它总是未定义有人有想法吗？

GetGlobalContext function and ClientGlobalContext.js.aspx (client-side reference) GetGlobalContext函数和ClientGlobalContext.js.aspx（客户端引用）
Use the GetGlobalContext function when programming with web resources to gain access to context information.
You can use the GetGlobalContext function when you include a reference to the ClientGlobalContext.js.aspx page located at the root of the web resources directory.
Couple more suggestions: 结合更多建议：
Webpage (HTML) web resources 网页（HTML）网络资源
Try dropping window from window.parent.Xrm.Page . 尝试从window.parent.Xrm.Page删除window 。
An HTML web resource added to a form can't use global objects defined by the JavaScript library loaded in the form.
Use IFRAME and web resource controls on a form 在表单上使用IFRAME和Web资源控件
Try passing inputs from form script. 尝试从表单脚本传递输入。
For webpage (HTML) web resources, use the setSrc method to manipulate the querystring parameter directly.
In an HTML page, the parameters can be accessed by using the window.location.search property in JavaScript.
Sample: Pass multiple values to a web resource through the data parameter 示例：通过data参数将多个值传递给Web资源

If you can not take the James Wood solution that is excellent try: 如果你不能采取优秀的詹姆斯伍德解决方案尝试：
1. You must check that your item is in an iframe 1.您必须检查您的商品是否在iframe中
You can get inspired by the following script: 您可以从以下脚本中获得灵感：
Xrm.Page.ui.controls.get('id_iframe').getObject().onload= function() {
var element = Xrm.Page.ui.controls.get('id_iframe').getObject().contentWindow.document.getElementById('id_element_inside_iframe');
console.log(element);
};
Xrm.Page.ui.controls.get('id_iframe').getObject(): Returns the HTML object iFrame Xrm.Page.ui.controls.get（'id_iframe'）。getObject（）：返回HTML对象iFrame
2. You could have an event called problem. 你可能会遇到一个叫做问题的事件。
You can get inspired by the following script: 您可以从以下脚本中获得灵感：
<HTML>
<BODY onload="SetupEvents()">
<label id="myLabel" >Click me</label>
</BODY>
<SCRIPT>
function DoTheThing() { alert('thing was done'); }
function SetupEvents() {
addEvent( document.getElementById('myLabel'),'click', function () { DoTheThing(); });
}
function addEvent(element, evnt, funct){
if (element.attachEvent)
return element.attachEvent('on'+evnt, funct);
else
return element.addEventListener(evnt, funct, false);
}
</SCRIPT>
</HTML>

I think this is a Turbo Forms issue since Turbo Forms loads Javascript in parallel and loads ClientGlobalContext.js.aspx as one of the last items. 我认为这是一个Turbo Forms问题，因为Turbo Forms并行加载Javascript并加载ClientGlobalContext.js.aspx作为最后一项。 IFrames contain an OnReadyStateCompleted event, I would suggest that you add the following code under that event. IFrame包含OnReadyStateCompleted事件，我建议您在该事件下添加以下代码。
function call() {
var phoneNumber = window.parent.Xrm.Page.getAttribute("mobilephone").getValue();
}

Let's say that your webresource is at root label... then you must add the ClientGlobalContext reference first 假设您的webresource位于根标签处...然后您必须首先添加ClientGlobalContext引用
<script src="ClientGlobalContext.js.aspx" type="text/javascript"></script>
After doing that you should be able to to get the attribute value with your function by just dropping the "window" part first 完成后，您应该能够通过首先删除"window"部分来获取函数的属性值
<script type="text/javascript">
function call() {
var phoneNumber = parent.Xrm.Page.getAttribute("mobilephone").getValue();
}
</script>
