具有多个事件处理程序传递参数的多个元素; d3.js;简化代码

Multiple elements with multiple event handlers passing parameters; d3.js; simplify code

如何动态生成这些事件处理程序?我想将其作为循环遍历 element.length.

的单个语句
    d3.select("#wordcloud_0_im").on("click", function(d,i)
    {
        var x =1;
        wordclouds(keyfile,start=(x-1)*wordcount,stop=x*wordcount);
    })
    d3.select("#wordcloud_1_im").on("click", function(d,i)
    {
        var x =2;
        wordclouds(keyfile,start=(x-1)*wordcount,stop=x*wordcount);
    })
    d3.select("#wordcloud_2_im").on("click", function(d,i)
   {
        var x =3;
        wordclouds(keyfile,start=(x-1)*wordcount,stop=x*wordcount);
    })

我不知道该怎么做。谢谢。

解决方案:

   function handleElement(i) {
        document.getElementById('wordcloud_' + i + '_im').onclick=function(d,e) {
            wordcount = 40;
            x=i;
            console.log("x :" + x);
            wordclouds(keyfile,start=(x-1)*wordcount,stop=x*wordcount);

        };
    }

     for(i=1; i<35; i++) 
        handleElement(i);
