我已经搜索了许多以前的回复，但没有一个对我有帮助。我实际上是在推断我之前发现的另一个脚本......但我不确定如何在 AJAX 中捕获响应。我猜测 handleResponse 只会捕获 checkdomain.cfm 上输出的任何内容，但我似乎无法做到这一点，所以我可以输出它。所以在下面的例子中，开发这个脚本的人不知何故能够从 checkdomain.cfm 中取回 AVAILABLE，但我不知道该怎么做。

提前致谢！

    <script>
        function handleResponse(s) {
            if(s == "AVAILABLE") {
                //rewrite span
                var domainspan = document.getElementById('DomainStatus');
                var newcontent = "Available To Register :)";
                domainspan.innerHTML = newcontent;
                var loadingspan = document.getElementById('frmGO');
                var newcontent = "<input name='' value='GO!' class='search_domain_go' type='submit' />";
                loadingspan.innerHTML = newcontent;
            } else {
                //rewrite span
                var domainspan = document.getElementById('DomainStatus');
                var newcontent = "Unavailable To Register :(";
                domainspan.innerHTML = newcontent;
                var loadingspan = document.getElementById('frmGO');
                var newcontent = "<input name='' value='GO!' class='search_domain_go' type='submit' />";
                loadingspan.innerHTML = newcontent;
            }
        }

        function CheckDomain() {
            var loadingspan = document.getElementById('frmGO');
            var newcontent = "<input name='' type='image' class='search_domain_go' src='images/ajax-loader.gif' alt='' />";
            loadingspan.innerHTML = newcontent;
            ColdFusion.Ajax.submitForm('frmDomainCheck','checkdomain.cfm',handleResponse);
        }
    </script>

我使用了您的代码，然后为 checkdomain.cfm 添加了以下内容

<cfoutput>AVAILABLE</cfoutput>

它工作得很好。在您的 handleResponse 函数中，alert(s);在顶部放置一条语句，以查看您从 checkdomain 返回的内容。
