如何编写 Javascript 函数来更新 Coldfusion 表单显示

Question

我正在开发一个应用程序，它有 2 个 Cfform 元素，显示来自 DB table 的结果。我想更新 DB table 的内容，并在不刷新页面的情况下更新 cfform 元素。我如何将 javascript 合并到我的代码中以在浏览器中不刷新整个页面的情况下处理异步刷新显示组件？

Answer 1

您只需通过 JQuery 拨打 JSON 电话。函数是 $.ajax、$.post 或 $.get.

有个whole example of AJAX with Coldfusion HERE

$.ajax({
  dataType: "json",
  url: url,
  data: data, // This is the request data
  done: function(json) {
    console.log(json);
    // Work with data
  }
});

解决方法如下：

将表单类型从 Flash 更改为 HTML。消除 CFformlayout 标签，因为它们只会造成不必要的麻烦。
以下代码提供了一个有效的 coldfusion 函数和 javascript 调用：

AJAX:

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<script language="javascript">

    $(document).ready(function() {
        $("#createReport").click(function(f) {
            var getReportName = $("input#reportName").val();
            var getReportPath = $("input#reportPath").val();
            var getReportDesc = $("input#reportDescrip").val();
            //var getCategory   = $("input#categoryBox").val();


            $.ajax({
                type:"POST",
                url: "http://10.11.2.60/testFolder/bidirectionalreporting/codetest/components/coldfusionFunction.cfc?method=testFunc&returnformat=json",
                dataType: "JSON",
                data:{ 
                        reportName: getReportName,
                        reportPath: getReportPath,
                        reportDescrip: getReportDesc
                        //categoryBox: getCategory

                },
                success: function(result){
                    alert("You successfully added a new report to the system") } 
    });
        });
    });     
</script>
