Jquery ajax call with '+' sign

$.ajax({  
        type: "POST", url: baseURL+"sys/formTipi_azioni",data:"az_tipo="+azione,
        beforeSend: function(){$("#form").html('<p><img src="'+baseURL+'lib/img/ajax-loader.gif" width="16" height="16" alt="loading" /><p>');},
        success: function(html){$("#form").html(html);}  
     });

there is a case when azione is

TB+ 

the plus sign doesn't get POSTed at all, a blank space 开发者_StackOverflowget sent. I already tried this:

azione = escape(String(azione));

With no luck. Does anybody knows how to fix this?

azione = escape(String(azione));

should be

azione = encodeURIComponent(String(azione));

or simply

azione = encodeURIComponent(azione);

Try this:

$.ajax({  
    type: "POST", 
    url: baseURL + "sys/formTipi_azioni",
    data: { az_tipo: azione },
    beforeSend: function(){
        $("#form").html('<p><img src="'+baseURL+'lib/img/ajax-loader.gif" width="16" height="16" alt="loading" /><p>');
    },
    success: function(html){
        $("#form").html(html);
    }  
});

and leave jQuery do the url encoding for you.

Never use escape(). Use encodeURIComponent().

Instead of trying to compose the post data yourself, you can also let jQuery do the work by passing it an object:

$.ajax({  
    type: "POST", url: baseURL+"sys/formTipi_azioni",
    data: {az_tipo: azione},
    beforeSend: function(){$("#form").html('<p><img src="'+baseURL+'lib/img/ajax-loader.gif" width="16" height="16" alt="loading" /><p>');},
    success: function(html){$("#form").html(html);}  
 });

you are looking for encodeURIComponent

escape(String(azione)).replace(new RegExp( "\\+", "g" ),"%2B");

this one sends the plus symbol with the help of regular expression
