这是我的调用模块(包括为网络资源)

module.buildFetchRequest = function (fetch) {

module.sendFetchQuery = function (fetchRequest, doneCallback, failCallback) {
//path to CRM root
var server = window.location.protocol + "//" + window.location.host;
//full path to CRM organization service - you may need to modify this depending on your particular situation
var path = server + "/XRMServices/2011/Organization.svc/web";
$.ajax({
type: "POST",
dataType: 'xml',
async: false,
contentType: "text/xml; charset=utf-8",
processData: false,
url: path,
data: fetchRequest,
beforeSend: function (xhr) {
xhr.setRequestHeader(
"SOAPAction",
"http://schemas.microsoft.com/xrm/2011/Contracts/Services/IOrganizationService/Execute"

}

.fail(failCallback);
};
}(window.xFetch = window.xFetch || {}));
用法(解析器需要 jQuery ...我在 web 资源 html 页面中进行大部分 fetch 调用,所以这不是问题)这在 IE 中有效,Chrome 没有检查 firefox,但我不明白为什么它会不行。
var fetchXml =
xFetch.buildFetchRequest("<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>" +
" <entity name='ENTITYNAME'>" +
" <attribute name='ATTRIBUTE' />" +
" </entity>" +
"</fetch>");
var entityList = new Array();
xFetch.sendFetchQuery(fetchXml,
function (fetchResponse) {
// chrome doesn't like the namespaces because of
// selectSingleNode implementations (which make sense btw)
// I'll never understand why Microsoft have to pepper their xml
// with namespace dross
$(fetchResponse).find("a\\:Entity, Entity").each(function () {
var entityData = {};
$(this).find("a\\:KeyValuePairOfstringanyType, KeyValuePairOfstringanyType").each(function () {
var xmlElement = $(this);
var key = xmlElement.find("b\\:key, key").text();
var value = xmlElement.find("b\\:value, value").text();
entityData[key] = value;
});
//inner loop
$(this).find("a\\:KeyValuePairOfstringstring, KeyValuePairOfstringstring").each(function () {
var xmlElement = $(this);
var key = xmlElement.find("b\\:key, key").text();
var value = xmlElement.find("b\\:value, value").text();
entityData[key] = value;
});
entityList.push(entityData);
});
}, function (jqXhr, textStatus, errorThrown) {
// if unsuccessful, generate an error alert message
});
for (var i = 0; i < entityList.length; i++) {
if (entityList[i].ATTRIBUTE === "Yes" ){
// DO WHATEVER
}
}
我只需要带有 KeyValuePairOfstringstring 和 KeyValuePairOfstringanyType 的属性,但是您可以使用正确的选择器组合解析出任何属性
