数据量太大时，如何实现分页查询-JSOM

利用Jsom实现分页查询：

var data=[];
function getItems()

{

licenceContext=new SP.ClientContext(); //var licenceContext =SP.ClientContext.get_current();

licenceWeb=licenceContext.get_web();
licenceList=licenceWeb.get_lists().getByTitle("listName");
query_licence=new SP.CamlQuery();

//需要哪些字段就将这些字段放到查询caml中，然后遍历时获取字段进行判断

var queryTemp='<View><ViewFields>'
+'<FieldRef Name="column1"/>'
+'<FieldRef Name="column2"/>'
+'<FieldRef Name="column3"/>'
+'</ViewFields><RowLimit>1000</RowLimit></View>';

//有时也会使用下列写法，但不一定有效

/*var queryTemp = "<View>"
+ "<Query><Where>"
+ "<And>"
+ "<IsNotNull><FieldRef Name='column1'/></IsNotNull>"
+ "<And>"
+ "<Eq><FieldRef Name='column2'/><Value Type='Text'>A</Value></Eq>"
+ "<Eq><FieldRef Name='column3'/><Value Type='Text'>Y</Value></Eq>"
+ "</And>"
+ "</And>"
+ "</Where><OrderBy><FieldRef Name='column1' Ascending='false'/></OrderBy></Query>"

+ "<ViewFields>"
+ "<FieldRef Name='column1'/>"
+ "<FieldRef Name='column2'/>"
+ "<FieldRef Name='Status'/>"
+ "<FieldRef Name='column3'/>"
+ "<FieldRef Name='column4'/>"
+ "</ViewFields>"
+ "<RowLimit>5000</RowLimit>"
+"</View>";*/

query_licence.set_viewXml(queryTemp);
licenceCollListItem=licenceList.getItems(query_licence);
licenceContext.load(licenceCollListItem);
licenceContext.executeQueryAsync(Function.createDelegate(this,onQuerySucceeded),Function.createDelegate(this,onQueryFailed));
}

function onQuerySucceeded(){ 

var listEnumerator=licenceCollListItem.getEnumerator();
while(listEnumerator.moveNext())
{
var testObj={};
var currentItem=listEnumerator.get_current();

var column1=currentItem.get_item('column1')||"";
var column2=currentItem.get_item("column2")||"";
var column3=currentItem.get_item("column23")||"";
testObj.column1=column1;
testObj.column2=column2;
testObj.column3=column3;
data.push(testObj);
}

var position = licenceCollListItem.get_listItemCollectionPosition();
if (position != null)
{
query_licence.set_listItemCollectionPosition(position);
licenceCollListItem = licenceList.getItems(query_licence);
licenceContext.load(licenceCollListItem);
licenceContext.executeQueryAsync(Function.createDelegate(this, onQuerySucceeded), Function.createDelegate(this,onQueryFailed));
}

else
{
　　var SkuObjColl=[];
　　SkuObjColl = data.where(function (z) { return z.column1 == "条件1"&& z.column2 == "条件2" });//linq条件筛选
}
SkuObjColl.forEach(function(result){//数据处理});
}

function onQueryFailed(sender, args) {
console.log('Request failed. \nError: ' + args.get_message() + '\nStackTrace: ' + args.get_stackTrace());
}
