如何在phonegap Android应用程序中创建会话

Question

我正在创建一个应用程序，我需要一个会话来存储userId，稍后我可以使用它从数据库中获取数据。我是phonegap的Android应用程序的新手，并没有任何关于会话的知识。所以任何人都可以给我一些例子或链接，我可以从中了解如何创建会话并使用它。 在此先感谢。 这里是js代码：

ftable=results.rows.item(i).from_table;//from database i am getting to know from which table to call for the select data option in dropdown list 
if(ftable.indexOf('#')=='-1'){ 
from_Table=ftable; 
}else{ 
//**in the from_table there is query which will need session data **// 
// from_Table="(select i.industry_id, i.industry_name, i.deleted, i.comp_code from user_industry_asso cuia, industry i where i.industry_id = cuia.industry_id and cuia.user_id = '1' order by i.industry_name)"; 
from_Table=""; 
split_table=ftable.split('#'); 


alert("Length: "+split_table.length); 
for(var k=0;k<split_table.length;k++){ 
    alert("After split: "+split_table[k]); 
    if(k%2==1){ 
     from_Table +=eval(split_table[k]); 
     alert("For loop if condition: "+from_Table); 
    }else{ 
     from_Table +=split_table[k]; 
     console.log("Else condition: "+from_Table); 
    } 
} 
} 
var select_optionData1="select "+optionName+"," +optionValue+" from "+from_Table+" alias where deleted='0' and comp_code='1' order by "+optionName; 
tx.executeSql(select_optionData1,[]);//will get the data from the table and store in array object which will be called later to create a dropdownlist 

这里是我在HTML文件中创建会话：

var userid='1'; 
window.sessionStorage.setItem('ls_userid',userid); 

var userId = window.sessionStorage.getItem('ls_userid'); 

Answer 1

对于存储会话，你可以使用localStorage的Follow this link

window.localStorage.setItem('ls_userid',userid); 
var userid = window.localStorage.getItem('ls_userid'); 
console.log(userid);
