Question

I need to disable the disable the submit button on my form and to enable if the onchange event occurs for any other input on the form
so basically I need to:

disable the submit button
add a method that enbales the submit button to the onchange event for all the other inputs on the form

任何人都知道如何这样做? (特别是第二)

Answer 1

利用j Query 1.4:

// To disable submit button
$( #myform ).find ( :submit ).attr ( disabled ,  disabled );

// Re-enable submit
var form = $( #myform );
$( :input , form.get(0)).live ( change , function (e) {
    form.find ( :submit ).removeAttr ( disabled );
});

Answer 2

为此:

$("form").submit(function() {
    $(this).find(":submit").attr("disabled", "disabled");
}).find(":input").change(function() {
    $(this).parent("form").find(":submit").removeAttr("disabled");
});

Answer 3

与此类似:

$("#myform").children().change(function(){
   $("#submit").removeAttr( disabled );
});
