How to prepend a string to a string variable in a for loop without changing the loop structure?

提问by some_bloody_fool

If i have a for loop like this:

如果我有这样的 for 循环：

var rows;
var len = z[0].length;
for ( var i = len; i--; ) {
     rows += "<tr><td>" + z[0].Marketer + "</td><td>";
 }

How can i prepend instead of append the current row to this string WithOUT changing the for loop structure?

如何在不更改 for 循环结构的情况下将当前行添加到该字符串中，而不是附加到该字符串中？

var rows;
var len = z[0].length;
for ( var i = len; i--; ) {
     rows (prepend) "<tr><td>" + z[0].Marketer + "</td><td>";
 }
