Hello, I have the following methods in javascript:

function buscarC(consulta) {
var result = "";
var buscado = "";
$.ajax({
    dataType: 'json',
    url: 'http://localhost:8080/tesisv2/webresources/generic/buscarxC?courseDisplayName=' + consulta['idCurso'] + '&page=1&row=' + consulta['row'],

    success: function (data) {
        var t = "";
        t = data.total;
        initpaginacion(t);            
        var nump;
        var n = consulta['row'];
        nump = Math.round(t / n);
        console.log(f);


        for (i = 0; i < data.elementos.length; i++) {

            buscado = '<tr class="recurso"><td>' + data.elementos[i][0] + '</a></td><td>' + data.elementos[i][1] + '</td><td>' + data.elementos[i][2] + '</td><td>' + data.elementos[i][3] + '</td><td>' + data.elementos[i][4] + '</td></tr>' + buscado;


        }

        result = '<style>table, th, td {  border: 1px solid black;}</style><table cellpadding="0" cellspacing="0" border="0" class="display" id="example"><thead><tr><th>Curso</th><th>IdEvento</th><th>Evento</th><th>Organizacion</th><th>PaisIP</th></tr></thead><tbody>' +
                buscado +
                '</tbody></table>';
        $("#contenido").html(result);
    },
    error: function () {

    }
});
}


function initpaginacion(resultadototal) {
if (total % numxpagina == 1) {
    totalpaginado = Math.trunc(resultadototal / numxpagina) + 1;
} else {
    totalpaginado = Math.trunc(resultadototal / numxpagina);
}
if (totalpaginado <= 0) {
    var paginado = "";
    document.getElementById('paginado').innerHTML = paginado;
} else {
    if (totalpaginado == last) {
        var paginado = "";
        paginado += '<ul class="pagination">';
        for (var i = init; i <= last; i++) {
            paginado += '    <li><a style="cursor:pointer;" id="pag' + i + '" onclick="buscar(' + false + ',' + i + ',' + numxpagina + ",'" + 'results' + "'" + ',null,this);"">' + i + '</a></li>';
        }
        paginado += '</ul>';
        document.getElementById('paginado').innerHTML = paginado;
    } else {
        var paginado = "";
        paginado += '<ul class="pagination">';
        for (var i = init; i <= last; i++) {
            paginado += '    <li><a style="cursor:pointer;" id="pag' + i + '" onclick="buscar(' + false + ',' + i + ',' + numxpagina + ",'" + 'results' + "'" + ',null,this);"">' + i + '</a></li>';
        }
        paginado += '    <li><a style="cursor:pointer;" onclick="next()">&raquo;</a></li>';
        paginado += '</ul>';
        document.getElementById('paginado').innerHTML = paginado;
    }
}
}

function buscar(a, b, c, d, e, f) {
alert(f.text);

}

I want to obtain the value of the variable f as seen in the search metere (with an alert that indicates its value), to use it in the method buscarC, how can I obtain that value to be able to use it in the method buscarC.

Hello, you can use global variables so that the searchC function has the answer of f, I'll give you an example:

var mensaje = “Mensaje de prueba”;


function muestraMensaje() {
  alert(mensaje);
}

For your case you must declare them as global

var a, b, c, d, e, f;
function buscarC(consulta) {...}
function buscar(a, b, c, d, e, f) {...}

You could generate a global variable (that is not inside any function) and assign the value of f to said variable in the function buscar .

var dato = "";

function buscar(a, b, c, d, e, f) {
   dato = f.text;
}

And then you can use that variable dato in the function buscarC .

function buscarC(consulta){
     //Tu código
     console.log(dato);
}
