javascript - 在 JavaScript 中传递变量 onclick

Question

好吧，伙计们，我正在尝试使用 getIndividualMap 函数中的变量，但收到 undefined 错误。可能是什么问题？

 var i; 
    for(i=0;i<=(data.length -1);i++)
    {   
    $('#ResultsId').append("<table border='1'>" + 

    "<tr>" +
    "<th>UserID</th>" +
    "<th>RUNDATE</th>" +
    "<th>NAME</th>" +
    "<th>TIME</th>" +
    "<th>DISTANCE (KM)</th>" +

    "</tr>" +
    "<tr>" + 
    "<td>" + data[i].UserID + "</td>"  + " " + 
    "<td>" + data[i].runDate + "</td>"  + " " + 
    "<td>" + data[i].firstName + "</td>"  + " " + 
    "<td>" + data[i].Time + "</td>"  + " " + 
    "<td>" + data[i].Distance + "</td>" + 
    "<td>" +"<a href='#' onclick= 'getIndividualMap(i)'>"  + data[i].UserID +"</a>" + "</td>" + 
    "</tr>" + 
    "</table>" );
    }


getIndividualMap(){
console.log(i);
}

Answer 1

函数参数变量缺失......

getIndividualMap(i){
console.log(i);
}

在下面的部分

"<td>" +"<a href='#' onclick= 'getIndividualMap(i)'>"  + data[i].UserID +"</a>" + "</td>" +

i 是硬编码的，但它是一个变量

应该是

"<td>" +"<a href='#' onclick= 'getIndividualMap("+ i + ")'>"  + data[i].UserID +"</a>" + "</td>" +
