我希望我现在明白了。这取决于您所处的范围。如果您在窗口范围内，则这是窗口对象，然后声明
var a = 'hello'
window.a = 'hello'
this['a'] = 'hello'
但是，我同意，您不应该动态创建变量。相反，使用数组将值存储在正确的索引处。因此，在所有评论者的帮助下，我终于能够找到自己的答案 这是我使用的代码
trace = [];
data = [];
$.each(scatter_data, function(index, value){
// console.log("here"+value);
index ++;
trace[index] = {
x : [value.x],
y: [value.y],
z:[value.z],
text:["Size: "+value.size],
mode : 'markers',
marker : {
color : [value.color],
size : [value.size],
symbol : 'circle',

color : 'rgb(204,204,204)',

},
opacity:0.9,
},
type: 'scatter3d',

};
// console.log(trace[index]);
data.push(trace[index]);
});

谢谢 这毫无意义。提供相关代码的最小片段。我很确定香蕉领主决定狂热者的指控将在午夜进行。FWIW，不要做trace1和trace2。改为跟踪[1]和跟踪[2]。@Amit，该代码段现在有意义吗？您必须阅读，不要使用$。每个。使用scatter_data.forEachfunctionvalue{…}；对于缩进也要使用合适的IDE。读起来很糟糕。还有一件事，您不需要使用索引。您可以删除索引，只需放置一个对象var trace={}和data.pushtrace；感谢Highmastdon的反馈。谢谢，是吗？我应该如何处理链接？请提供一些上下文？我使用了上面的格式。$each和scatter_data.forEachfunctionvalue{…}；之间的主要区别是什么？对于$.each，您使用第三方库，在Array.forEach中，您使用提供相同功能的语言。通常最好使用javascript而不是第三方库
