我的javascript for循环仅从3行的数组中打印出1行

Question

我不知道在for循环中正确的条件应该是什么，该循环遍历一个数组，该数组的长度根据我要从中添加并添加到该数组的表中的行数而变化。 该数组当前有三行，但是for循环仅打印出两行。 我的代码：

//my database query 

query.find({
  success: function(results) {

//this for loop works fine

    for (i = 0; i < results.length; i++){

        eventID = results[i].id;
       activity = results[i].get("activity");
        scene = results[i].get("location");
        neighborhood = results[i].get("neighborhood");
        date = results[i].get("date");
        details = results[i].get("details");
        time = results[i].get("time");
        objIDs.push(eventID);

//each row gets pushed into an array

       search.push([activity, scene, neighborhood, date, details, time]);


        //I empty a div on a page that uses the ajax load() method to load an html page.I replace that html with the array of query results. 

             $('#div1').empty();

       //there are currently 3 rows in my array, but when I loop through it and append() the </br>rows to the div, only one gets printed. I've tried changing the comparison operator to </br>different things but nothing works. I'm definitely getting all the rows from the query because when I alert() the search array I see all the rows. 

       for (i = 0; i <= search.length; i++) {

            $('#mainDiv').append("<div id='event'>" + search[i].join(' ') + "<a href='#' class='interested'>Interested?</a></div>");
        } 

    };// closes for
    },//closes success

  error: function(error) {
    alert("Error: " + error.code + " " + error.message);
  }
}); //closes find

虽然下面是一个问题，这可能不是问题。 但是，由于我无法删除此帖子（我必须登录或进行其他操作？），因此它仍为工件。 即使问题是其他原因，也请注意。

该代码在嵌套循环中使用相同的i变量-并在两个循环中递增i 。

使用其他变量。

您for内部有一个for ， for您对其进行迭代时尚未完全初始化搜索。

};// closes for

    for (i = 0; i <= search.length; i++) {

        $('#mainDiv').append("<div id='event'>" + search[i].join(' ') + "<a href='#' class='interested'>Interested?</a></div>");
    } 

},//closes success
