Question

我搜索了之前的一些回复，但没有一个回应过我。我实际上正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。我猜是handleResponse会捕获checkdomain.cfm上输出的内容，但我似乎无法实现这一点，所以我可以输出它。所以在下面的例子中，开发此脚本的人能够以某种方式从checkdomain.cfm返回AVAILABLE，但我无法弄清楚如何做到这一点。

提前致谢！

<cfajaximport />

    <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);

Answer 1

我使用了您的代码，然后为checkdomain.cfm添加了以下内容

<cfoutput>AVAILABLE</cfoutput>

它运作得很好。在handleResponse函数中，在顶部放置一个alert(s);语句，以查看您从checkdomain获取的内容。
