如何在CRM Online 2013中使用Javascript查询记录注释中保存的图像
我的实体中的每个记录都附有一张图像。我想在web资源中的记录中显示这些图像,就像记录图片一样。我正在使用以下代码:如何在CRM Online 2013中使用Javascript查询记录注释中保存的图像,javascript,dynamics-crm-2011,odata,crm,dynamics-crm-online,Javascript,Dynamics Crm 2011,Odata,Crm,Dynamics Crm Online,我的实体中的每个记录都附有一张图像。我想在web资源中的记录中显示这些图像,就像记录图片一样。我正在使用以下代码: function GetData(){ // var base64image = document.getElementById('image').src.substr(document.getElementById('image').src.indexOf('base64')+7); var recordId = window.parent.Xrm.Page.data
function GetData(){
// var base64image = document.getElementById('image').src.substr(document.getElementById('image').src.indexOf('base64')+7);

alert("success paa jee!!");

</script>
函数GetData(){
//var base64image=document.getElementById('image').src.substr(document.getElementById('image').src.indexOf('base64')+7);
var recordId=window.parent.Xrm.Page.data.entity.getId();
var serverUrl=Xrm.Page.context.getServerUrl().toString();
var ODATA_ENDPOINT=“XRMServices/2011/OrganizationData.svc”;
var objAnnotation=新对象();
var ODATA_EntityCollection=“/AnnotationSet”;
var temp=“/AnnotationSet?$select=DocumentBody,FileName,MimeType,ObjectId&$filter=ObjectId/Id eq guid'+recordId+”;
var结果=服务器URL+ODATA_端点+ODATA_EntityCollection+temp;
//将实体对象解析为JSON
var jsonEntity=window.JSON.stringify(objAnnotation);
//使用OData创建CRM记录的异步AJAX函数
$.ajax({
键入:“获取”,
contentType:“应用程序/json;字符集=utf-8”,
数据类型:“json”,
url:结果,
//数据:JSONENITY,
async:false,
beforeSend:函数(XMLHttpRequest){
setRequestHeader(“接受”、“应用程序/json”);
},
成功:功能(状态){
警惕(“成功帕吉!!”);
},
错误:函数(xmlHttpRequest、textStatus、errorshown){
警报(“状态:+textStatus+”;错误抛出:+Error抛出);
}
});
}
但是当我到达Ajax部分时,我得到一个错误,$未定义。基本上,每个记录的注释中都有一个图像附在实体的记录上,我想在web资源中将此图像显示为记录图片
如果有更好的/另一种方法,我愿意接受建议
编辑:我已经编辑了代码并更新了ODataURL 在CRM 2011中,我使用了两个自定义Aspx页面
来显示所附图像
第1页:AccountImage.aspx具有以下控件:
<asp:Image ID="IMG_Logo" runat="server" Height="50px" ImageUrl="AccountImageForm.aspx" Visible="false" />
ShowImages()
函数包含以下代码:
function ShowImages()
{
IMG_Logo.Visible = false;
QueryExpression query = new QueryExpression("annotation");
query.Criteria.AddCondition("objectid", ConditionOperator.Equal, Id);
query.Criteria.AddCondition("mimetype", ConditionOperator.In, new string[] { "image/x-png", "image/pjpeg", "image/png", "image/jpeg" });
query.Criteria.AddCondition("subject", ConditionOperator.NotEqual, "membershipcardthumbnail");
query.Criteria.AddCondition("subject", ConditionOperator.NotEqual, "membershipcardimage");
query.ColumnSet = new ColumnSet(true);
EntityCollection AllLogoImageNotes = Common.Common.RetrieveMultiple(query);
if (AllLogoImageNotes.Entities.Count > 0)
{
foreach (Entity Note in AllLogoImageNotes.Entities)
{
if (Note.Attributes.Contains("subject") && Note.Attributes.Contains("documentbody"))
{
if (Note["subject"].ToString().ToLower() == "accountlogoimage")
{
HttpRuntime.Cache.Remove("AccountLogoImage");
HttpRuntime.Cache.Remove("AccountLogoImageType");
HttpRuntime.Cache.Add("AccountLogoImage", Convert.FromBase64String(Note["documentbody"].ToString()), null, DateTime.Now.AddMinutes(5), TimeSpan.Zero, CacheItemPriority.Normal, null);
HttpRuntime.Cache.Add("AccountLogoImageType", Note["mimetype"].ToString(), null, DateTime.Now.AddMinutes(5), TimeSpan.Zero, CacheItemPriority.Normal, null);
IMG_Logo.ImageUrl = "AccountImageForm.aspx" + "?time=" + DateTime.Now.ToString();
IMG_Logo.Visible = true;
}
}
}
}
}
protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
if (HttpRuntime.Cache["AccountLogoImage"] != null)
{
Response.ContentType = HttpRuntime.Cache["AccountLogoImageType"].ToString();
byte[] data = (byte[])HttpRuntime.Cache["AccountLogoImage"];
Response.BinaryWrite(data);
}
}
如您所见,下面的行:
IMG_Logo.ImageUrl=“AccountImageForm.aspx”+”?time=“+DateTime.Now.ToString()代码>
在AccountImageForm.aspx
中编写以下代码:
function ShowImages()
{
IMG_Logo.Visible = false;
QueryExpression query = new QueryExpression("annotation");
query.Criteria.AddCondition("objectid", ConditionOperator.Equal, Id);
query.Criteria.AddCondition("mimetype", ConditionOperator.In, new string[] { "image/x-png", "image/pjpeg", "image/png", "image/jpeg" });
query.Criteria.AddCondition("subject", ConditionOperator.NotEqual, "membershipcardthumbnail");
query.Criteria.AddCondition("subject", ConditionOperator.NotEqual, "membershipcardimage");
query.ColumnSet = new ColumnSet(true);
EntityCollection AllLogoImageNotes = Common.Common.RetrieveMultiple(query);
if (AllLogoImageNotes.Entities.Count > 0)
{
foreach (Entity Note in AllLogoImageNotes.Entities)
{
if (Note.Attributes.Contains("subject") && Note.Attributes.Contains("documentbody"))
{
if (Note["subject"].ToString().ToLower() == "accountlogoimage")
{
HttpRuntime.Cache.Remove("AccountLogoImage");
HttpRuntime.Cache.Remove("AccountLogoImageType");
HttpRuntime.Cache.Add("AccountLogoImage", Convert.FromBase64String(Note["documentbody"].ToString()), null, DateTime.Now.AddMinutes(5), TimeSpan.Zero, CacheItemPriority.Normal, null);
HttpRuntime.Cache.Add("AccountLogoImageType", Note["mimetype"].ToString(), null, DateTime.Now.AddMinutes(5), TimeSpan.Zero, CacheItemPriority.Normal, null);
IMG_Logo.ImageUrl = "AccountImageForm.aspx" + "?time=" + DateTime.Now.ToString();
IMG_Logo.Visible = true;
}
}
}
}
}
protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
if (HttpRuntime.Cache["AccountLogoImage"] != null)
{
Response.ContentType = HttpRuntime.Cache["AccountLogoImageType"].ToString();
byte[] data = (byte[])HttpRuntime.Cache["AccountLogoImage"];
Response.BinaryWrite(data);
}
}
在ODATA中,您可以执行以下操作:
retrieveImages("/AnnotationSet?$select=DocumentBody,MimeType&$filter=ObjectId/Id eq guid'" + Xrm.Page.data.entity.getId()+ "'", function (JsonObject) {
if (JsonObject != null) {
// debugger;
var ByteString= JsonObject[0].DocumentBody;
var MimeType = JsonObject[0].MimeType
}
function retrieveImages(query, SuccessFunc) {
var retrieveRecordsReq = new XMLHttpRequest();
var ODataPath = Xrm.Page.context.getServerUrl() + "/xrmservices/2011/OrganizationData.svc";
retrieveRecordsReq.open('GET', ODataPath + query, false);
retrieveRecordsReq.setRequestHeader("Accept", "application/json");
retrieveRecordsReq.setRequestHeader("Content-Type", "application/json; charset=utf-8");
retrieveRecordsReq.onreadystatechange = function () {
if (this.readyState == 4 /* complete */) {
if (this.status == 200) {
this.onreadystatechange = null; //avoids memory leaks
var data = JSON.parse(this.responseText, SDK.REST._dateReviver);
if (data && data.d && data.d.results)
SuccessFunc(JSON.parse(this.responseText, SDK.REST._dateReviver).d.results);
}
else {
alert(SDK.REST._errorHandler(this));
}
}
};
retrieveRecordsReq.send();
}
没有办法通过ODATA做到这一点。我似乎想不出所需的查询程序。您如何在crm中上载aspx页面?@hkhan您必须将aspx页面作为单独的网站或ISV文件夹上载到crm服务器。然后使用IFrame显示页面。我不认为你们可以在CRM Online中这样做。这就是为什么我要使用javascript和OData。由于缺少一些括号,我不得不对代码进行一些更改,但这确实起到了作用……现在下一步是显示检索到的图像。谢谢小多特。
