Coldfusion Ajax - 表单提交

发布于 2024-09-06 13:23:01 字数 272 浏览 6 评论 0原文

我需要 ColdFusion 方面的帮助，我想使用 CF9 ajax 库，我的标头中有，并包含一个使用 < cfdiv bind="url:domainchecker.cfm"> 然而，这会用“正在加载”ajax 轮替换整个表单，然后显示结果。

我需要的是提交表单，但是单独的结果区域会被更新（并且显然会有ajax“加载”）。我不想改变整个区域（这有意义吗？？）

因此，经过一番深思熟虑，我做到了：

<head>
...
<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);
        }
    </script>
...
</head>

<body>
...
        <div class="search_domain">
            <div class="search_domain_form">
            Search Your Domain Here<br />
                <form method="post" action="" onSubmit="CheckDomain();return false;" id="frmDomainCheck">
                    <input class="search_domain" name="frmURL" id="frmURL" value="Please enter your domain name here..." onfocus="if(this.value == 'Please enter your domain name here...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Please enter your domain name here...';}" type="text" />
                    <span id="frmGO"><input name="" value="GO!" class="search_domain_go" type="submit" /></span>
                <form>
            </div><!-- /# end search form -->
            <div class="domain_features">
                <ul>
                    <li><span id="DomainStatus">Type in the domain and click 'GO' to check its availability.</span></li>
                </ul>
            </div>
        </div>
...
</body>

So, after much soul searching, I managed this:

<head>
...
<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);
        }
    </script>
...
</head>

<body>
...
        <div class="search_domain">
            <div class="search_domain_form">
            Search Your Domain Here<br />
                <form method="post" action="" onSubmit="CheckDomain();return false;" id="frmDomainCheck">
                    <input class="search_domain" name="frmURL" id="frmURL" value="Please enter your domain name here..." onfocus="if(this.value == 'Please enter your domain name here...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Please enter your domain name here...';}" type="text" />
                    <span id="frmGO"><input name="" value="GO!" class="search_domain_go" type="submit" /></span>
                <form>
            </div><!-- /# end search form -->
            <div class="domain_features">
                <ul>
                    <li><span id="DomainStatus">Type in the domain and click 'GO' to check its availability.</span></li>
                </ul>
            </div>
        </div>
...
</body>

我个人会使用 jQuery 而不是 CF Ajax 函数来实现简单绑定以外的功能，而无需太多额外的 JavaScript。

CF 提供的 JavaScript 函数只是太有限了。

由于您已经使用过 jQuery，这应该很容易。看看Ajax + jQuery 的操作函数。

保持简单吗？

域搜索.cfm

<head>
</head>

<body>
<h2 style="color:Blue">Domain search</h2>
<form name="domainSearch">
www.<input class="search_domain" name="searchString" id="frmURL" value="Please enter your domain" onfocus="if(this.value == 'Please enter your domain') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Please enter your domain';}" type="text" />.com
<font color="#FF0000"><strong>[Search]</strong></font>
</form>
<p>Enter any domain.com, (hint: try "free")</p>
<cfdiv id="resultsDiv" bind="url:searchProcessor.cfm?searchString={searchString}">
</body>
</html>

搜索处理器.cfm

<cfif IsDefined("URL.searchString")>

    <cfif URL.searchString eq "Please enter your domain">
        <cfoutput></cfoutput>   
    <cfelseif URL.searchString eq "free">
        <cfoutput>Great, #URL.searchString# is available, price $400</cfoutput>
    <cfelse>    
        <cfoutput>Sorry, #URL.searchString# is not available, try again.</cfoutput>
    </cfif>
</cfif>

Keep it simple?

domainSearch.cfm

<head>
</head>

<body>
<h2 style="color:Blue">Domain search</h2>
<form name="domainSearch">
www.<input class="search_domain" name="searchString" id="frmURL" value="Please enter your domain" onfocus="if(this.value == 'Please enter your domain') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Please enter your domain';}" type="text" />.com
<font color="#FF0000"><strong>[Search]</strong></font>
</form>
<p>Enter any domain.com, (hint: try "free")</p>
<cfdiv id="resultsDiv" bind="url:searchProcessor.cfm?searchString={searchString}">
</body>
</html>

searchProcessor.cfm

<cfif IsDefined("URL.searchString")>

    <cfif URL.searchString eq "Please enter your domain">
        <cfoutput></cfoutput>   
    <cfelseif URL.searchString eq "free">
        <cfoutput>Great, #URL.searchString# is available, price $400</cfoutput>
    <cfelse>    
        <cfoutput>Sorry, #URL.searchString# is not available, try again.</cfoutput>
    </cfif>
</cfif>
