Just set a button redirect to the page you want to go.
Don't know to reason why you would pre-load your page but IIS or Appache can pre-load you page. You don't have to worry about that.

iis: pre load settings

If the page is on what kinda reason slow than fix that problem.

What I wanna make is only to call my function, as the page don´t load my script, so I inserted the button to load the script, but for this , I have that click in my button to show this. So I wanna make a button pre clicked.

To call another page is not my intention.
I´m using phonegap, maybe be for this reason that it not function.

Is the LoadSecondPage() function on the same page? Maybe you can post the script in your solution. I would suggest you to use document on ready like this fiddle: https://jsfiddle.net/pitasato/9xuxntpL/

It works of same form, but show me a follow error:" Uncaught TypeError: Cannot read property 'transaction' of null"

code| index2.js

function pesquisarTela(){

var recebe = $.urlParam('id_titulo');

alert("id= "+recebe);

// var var_texto = document.getElementById("texto").value;
//var var_query = "SELECT * FROM estudos WHERE titulo like '%"+var_texto+"%' ";
// var var_query = "SELECT * FROM vtestudos WHERE vtestudos MATCH '*"+var_texto+"*' ";

var teste="select titulo,texto from vtestudos where id_titulo="+recebe;
//var teste = "select * from vtestudos";
//var var_query = "SELECT * FROM vtestudos WHERE vtestudos MATCH 'teste' ";
//alert(var_query);

//var var_query = "SELECT count(*) as qtd FROM vtestudos";

~~--- show me error in this line --> db.transaction(function(tx) {~~
tx.executeSql(teste, [], function(tx,res){
//alert(res.rows.length);
//alert(res.rows.item(0).qtd);

if(res.rows.length > 0)
{
var var_div_retorno = "";
for (var i = 0; i < res.rows.length; i++){

var var_div_retorno = var_div_retorno + "";

var var_div_retorno = var_div_retorno + "";

var var_div_retorno = var_div_retorno + ""

}
var var_div_retorno = var_div_retorno + "";
var var_div_retorno = var_div_retorno + res.rows.item(i).titulo;
var var_div_retorno = var_div_retorno + "";
var var_div_retorno = var_div_retorno + res.rows.item(i).texto;
var var_div_retorno = var_div_retorno + ""
var var_div_retorno = var_div_retorno + ""
var var_div_retorno = var_div_retorno + "";
}

//alert(var_div_retorno);
document.getElementById("div_retorno").innerHTML = var_div_retorno;

});
}, function(err){
alert(err.message);
});

}

So, looks like me insolvable ...

This is a database error: 'Uncaught TypeError: Cannot read property 'transaction' of null"'
I should post that in a new question and accept this one. Can be everything.
If you comment all your database lines in the script it works?

MarkNopfler 3-May-17 12:06pm

Right. If I comment all command line part that envolve database , so IT don´t will return the values, but follow without errors.. But I need from my line that envolve database in command line.
