rexseeCallLog對象，實現自定義數量的最近通話記錄，自定義查詢最近通話，讀取記錄數據庫表的URI地址。。html

【函數】 JsonObjectArray get(int number)java

【說明】獲取指定數量的最近通話。android

【返回】 Json對象數組，使用eval('('+json+')')轉換爲JavaScript對象數組。數據庫

【參數】 number：要獲取的最近通話的數量。express

【示例】 json

alert(rexseeCallLog.get(10));

【函數】 JsonObjectArray get(String type, int number)數組

【說明】獲取值類型、指定數量的最近通話。app

【返回】 Json對象數組，使用eval('('+json+')')轉換爲JavaScript對象數組。less

【參數】 type：類型，"INCOMING"(數據庫中爲1)、"OUTGOING"(數據庫中爲2)或"MISSED"(數據庫中爲3)。ide

number：要獲取的最近通話的數量。

【示例】

alert(rexseeCallLog.get('INCOMING',10));
alert(rexseeCallLog.get('OUTGOING',10));
alert(rexseeCallLog.get('MISSED',10));

【函數】 JsonArray getColumns()

【說明】獲取通話記錄數據表全部字段。

【返回】 Json數組，使用eval('('+json+')')轉換爲JavaScript數組，注意，爲了提升效率，調用get()或getData()時並不會返回其中全部字段。

【參數】無

【示例】

alert(rexseeCallLog.getColumns());

【函數】 JsonObjectArray getData(String selection, int number)

【說明】獲取自定義查詢條件的最近通話。

【返回】 Json對象數組，使用eval('('+json+')')轉換爲JavaScript對象數組。

【參數】 selection：自定義查詢條件，至關於SQL語句中的WHERE字句（不含單詞WHERE）。

number：要獲取的最近通話的數量。

【示例】

alert(rexseeCallLog.getData('duration<10',10));
