javascript - 如何从 javascript 图表触发 ajax

Question

Javascript菜鸟。我有一个来自 spring.js 的强制有向图，我想在用户选择一个节点时从中触发 ajax，但我不断收到错误未捕获的语法错误:意外的标记。这集中在该行

function GetSpringyNode(node.data.label){ 

。我已经设法让它触发警报，但触发 ajax 很棘手。谁能告诉我怎么做？我认为问题的关键是如何将node.data.label传递给ajax。这是jsfiddle下面是我正在尝试的代码:

var graphJSON = <%=raw @users.to_json %>;
 var graph = new Springy.Graph();
 graph.loadJSON(graphJSON);
 var springy = jQuery('#springydemo').springy({graph: graph});


jQuery('#springydemo').springy({ graph: graph, nodeSelected: function(GetSpringyNode) {
    alert(node.data.label);
} });


                function GetSpringyNode(node.data.label){
                 $.ajax({
          url: "/users/show", 
          type: "GET", 
          dataType: 'html',
          data: {name: d.name},
          success: function(result) {
            //$('#NodeProfile').html(result);
            //$('.bchart-content').html(result);
            //Need to parse into html here before included in .bchart-content
            addGraph(result);
          }
        });
      }

将代码更改为:

jQuery('#springydemo').springy({ graph: graph, nodeSelected: function() {
    GetSpringyNode(node.data.label);
} });

和 GetSpringyNode 函数:

function GetSpringyNode(label){
    $.ajax({
        url: "/users/show", 
        type: "GET", 
        dataType: 'html',
        data: {name: label},
        success: function(result) {
        //$('#NodeProfile').html(result);
        //$('.bchart-content').html(result);
        //Need to parse into html here before included in .bchart-content
            addGraph(result);
        }
    });
}
