I use the code below to send a meter in a request Ajax of the kind GET.

$('#cidades').load('cidades.php?estado=' + $('#estados').val());

How do I also pass a parameter called recurso?

javascript jquery get

  • What is the variable name?

  • did not understand the difficulty. After all, it is already concatenating a parameter. Then just follow the logic and concatenate another... +"&outro_parametro=valor"

  • The variable name is: resource

  • What is wrong with this concatenation? $('#transacao').load('transacao.php?estado='+$('#estados').val()+'&cliente='+idcl+'&teste='+idcl);

  • Gladison, any answers to your problem? It is interesting to give feedback, because someone else may have the same problem, and when you get here you will know what was done. : ) See here what you can do by getting an answer to your question. ;)

Another way is to send an object as "second parameter", according to the jQuery.load documentation().

var parametros = {
    estado: $('#estados').val(),
    recurso: $('#recurso').val()
};

$('#cidades').load('cidades.php', parametros, callback);

var callback = function() {
    //do something
}

It is still possible to call a callback function as the third parameter.

    +1 for the "second argument". It’s always better to use a jQuery feature in jQuery itself than to concatenate (something jQuery does internally in this case)

If you continue with this concatenation there in your code, it would be preferable to use the function $.param jQuery.

var dados = {
   estado: $('#estados').val()
}

var  url = 'cidades.php?' + $.param(dados)

But anyway I consider the answer of @Pedrojuniorcamara better solution

  • +1 for the use of $.param, I did not know this function, it is very useful.

    jQuery uses it internally when you use the attribute data ajax as an object ;)

You just need to separate the variables with the character &

$('#cidades').load('cidades.php?estado='+$('#estados').val()+'&recurso=seuRecurso');

If you need to use more parameters, I think it’s much better that you do it the way Pedro and Wallace said.

  • Concatenation is the ugliest thing in programming, right, @jbueno ?!?! + 1

  • Yeah? I don’t know @Wallacemaxters

  • Hello, this your script worked perfectly, but so that I can better use these features and implement more parameters, how do I make the IDCL variable used in the parameter to receive a content coming from a php variable? Take a look below: $('#cities'). load('cities.php? status='+$('#states'). val()+'&client='+idcl);

  • @jbueno I don’t like to concatenate (at least in the three languages I most move, I think ugly [python, php, javascript])

  • If you need to use more parameters, I think much You better do it the way Pedro and Wallace said. As for your other question, I think it’s a subject for another question, you can ask as many times as you need (as long as you have common sense, of course).

  • agree, fully. but my doubt now is on how to receive the value of a php variable and put inside the IDCL variable. Because even using the way of the colleagues above, I will always need to receive value of variables of another language.

  • Like I don’t like @Wallacemaxters either, but that doesn’t make me avoid it at all costs. As I assumed that he would need to pass one or two parameters I did so, but as I said, if you start putting more it already gets ugly and has shapes well better to do (as in other answers).

  • That’s another problem @Gladisonneuzaperosini. If it’s another problem, you need another question.

  • @jbueno I understood what I said. After all, even for some types of return I am obliged to concatenate, sometimes in the very libraries I develop.

  • What is wrong with this concatenation? $('#transacao'). load('transacao.php? status='+$('#states'). val()+'&client='+idcl+'&teste='+idcl);

  • What’s the problem with the answer?

The parameters should be separator by a "&" thus:

link.php?param1=valor&param2=valor

In your example would look something like:

cidades.php?estado=valor&cidade=valor
