I am performing several dozen SQLite CRUD operations in my app. I am curious if I can send custom function calls as parameters in the following sample. I will explain.
The code below shows how I query a “customer” table and then fill an input control datalist.
I call this function to kick it off:
function GetContractListByCustomerId(customer_id) {
arg = [customer_id];
var s = new Array(['SELECT id, contract_name, customer_id FROM contract WHERE customer_id=?;', arg, ResultsToHomeContractInput]);
Sql(DB, s);
}
Then you can see in the Sql function I have a success callback as shown below. This callback receives the transaction object and the results array of the select query.
function ResultsToHomeContractInput(transaction, results)
{
DBRecords = results;
var arrContracts = [];
for(i=0; i<=DBRecords.rows.length-1; i++){
arrContracts.push(DBRecords.rows.item(i)['contract_name']);
}
inputContract.datalist = arrContracts;
imageBusy.hidden=true;
}
This code works great but what I am finding is that I want to add some dynamic function calls to the callback results. So lets say that I want the above sample to look like below. If I add a function variable as a parameter, can I send that variable as a parameter to the Sql success callback function?
function GetContractListByCustomerId(customer_id, **functionNameVar**) {
arg = [customer_id];
var s = new Array(['SELECT id, contract_name, customer_id FROM contract WHERE customer_id=?;', arg, ResultsToHomeContractInput(**functionNameVar**)]);
Sql(DB, s);
}
What would that look like in the callback itself? The parameters “transaction” and “results” are added.
function ResultsToHomeContractInput(transaction, results, **functionNameVar**)
{
DBRecords = results;
var arrContracts = [];
for(i=0; i<=DBRecords.rows.length-1; i++){
arrContracts.push(DBRecords.rows.item(i)['contract_name']);
}
inputContract.datalist = arrContracts;
imageBusy.hidden=true;
-->>> Call the function variable **functionNameVar** here???
}
