javascript - jQuery Ajax 错误 - 堆栈跟踪

Question

如何从 jQuery Ajax Error 获取堆栈跟踪.

Answer 1

有些人可能想知道如何评估调用成功/错误的源 ajax 调用的堆栈，因为这发生在新线程中。以下内容可能对解决这个老问题的人有用:

var callingState = new Error(); // capture state/stack when ajax is called
jQuery.ajax({// just showing error property
    error: function() {
        // employ "closure" to access values from the ajax context
        // access stack showing context when ajax was called
        alert('Caller stack: ' + callingState.stack);
        // access stack during "error" callback
        alert('Current stack: ' + (new Error()).stack);
    }
});
