javascript – jquery deferred – 等到两个电话完成

$.whenAllDone = function() {
    var deferreds = [];
    var result = $.Deferred();

    $.each(arguments,function(i,current) {
        var currentDeferred = $.Deferred();
        current.then(function() {
            currentDeferred.resolve(false,arguments);
        },function() {
            currentDeferred.resolve(true,arguments);
        });
        deferreds.push(currentDeferred);
    });

    $.when.apply($,deferreds).then(function() {
        var @R_516_4895@ = [];
        var successes = [];

        $.each(arguments,args) {
            // If we resolved with `true` as the first parameter
            // we have a failure,a success otherwise
            var target = args[0] ? @R_516_4895@ : successes;
            var data = args[1];
            // Push either all arguments or the only one
            target.push(data.length === 1 ? data[0] : args);
        });

        if(@R_516_4895@.length) {
            return result.reject.apply(result,@R_516_4895@);
        }

        return result.resolve.apply(result,successes);
    });

    return result;
}

查看this Fiddle看看它是如何工作的.

基本上,等待所有Deferreds完成,无论他们是否失败,并收集所有的结果.如果我们有失败,返回的Deferred将失败并列出所有故障,否则解决所有成功.
