Ajax函数和异步：false

Question

here got a weird situation .....

i got a function that cannot edit.(for some reason and i need to use it instead of create a new 1, or overwrite the script is not allowed...)

function update_tpl2(form, divtoupdate, exeAlert) {
if(!$('#'+form).length)
    form = 'myform';
if(!$('#'+divtoupdate).length)
    divtoupdate = 'ajax_update';

$.ajax({
    type: "POST",
    url: url,
    data: $('#' + form).serialize(),
    dataType: "html",
    beforeSend: ShowLoading,
    success: function(resp){
        $('#theLoading').dialog('close');
        $('#loading').html('');         
        $('#' + divtoupdate).html(resp);
    }
});

}

and i need to add async: false into that function when run. is there any way to set the ajax to async: false, by not changing the function and using it.....

Answer 1

Something like this perhaps?

just call the following function with properties = { async: false }

function update_tpl2(form, divtoupdate, exeAlert, properties) {
if(!$('#'+form).length)
    form = 'myform';
if(!$('#'+divtoupdate).length)
    divtoupdate = 'ajax_update';

var defaultProps = {
    type: "POST",
    url: url,
    data: $('#' + form).serialize(),
    dataType: "html",
    beforeSend: ShowLoading,
    success: function(resp){
        $('#theLoading').dialog('close');
        $('#loading').html('');         
        $('#' + divtoupdate).html(resp);
    }
}

jQuery.extend( true, defaultProps, properties)

$.ajax(defaultProps);
