$('input').each(function(){
var id = $(this).attr('id');
var class = $(this).attr('class');
var val = $(this).val();
if(val.length == 0){
alert('Error');
return false;
}
//HERE STOP UNTIL ALL IS OK
var data = '?id=' + id + '&class=' + class + '&val=' + val;
$.ajax({
type: 'POST',
url: url,
data: data,
success: success,
dataType: dataType
});
})
如何制作?我想只在所有输入都有长度>时才使用$ .ajax。 0.
例如,如果我有输入:
1: [aaa]
2: [asad]
3: []
4: [sdfs]
然后
1: - no error and send with ajax
2: - no error and send with ajax
3: - error and not send with - ajax previous return false
4: - stop script
在这个例子中应该是:
1: - no error - add to array and wait - not send with ajax
2: - no error - add to array and wait - not send with ajax
3: - error stop script - any data not send with ajax.
我想只在所有值都正常的情况下发送ajax。我该怎么做?

一个选项是迭代两次,并使用指标/标志变量来跟踪任何验证是否失败:
var valid = true;
$('input').each(function(){
if($(this).val().length == 0){
alert('Error');
valid = false;
return false;
}
});
if(valid)
$('input').each(function(){
var id = $(this).attr('id');
var class = $(this).attr('class');
var val = $(this).val();
var data = '?id=' + id + '&class=' + class + '&val=' + val;
$.ajax({
type: 'POST',
url: url,
data: data,
success: success,
dataType: dataType
});
});
