我是Json和Javascript的新手。 我正在尝试使用for循环来动态显示匹配的名称数据但我被困在这里请帮助.for循环没有正确显示数据。它直接进入最后一个指数（即杀手Agen 47）。

您每次都会覆盖VSFlexShift.set_TextMatrix(i, 2, objShiftMasterDTO.SHIFT_START.ToString(@"hh\:mm\:ss"));
并丢失之前计算的结果。
innerHTML您需要使用for(i=0; i<array.length; i++){
if(input_txt.innerHTML.toUpperCase == array[i].name.toUpperCase ){
box1.innerHTML = array[i].name + "<br>"
}
}
运算符附加HTML，以便获得所有结果，但不仅仅是最后一个结果：
+顺便说一句，比较for(i=0; i<array.length; i++){
if(input_txt.innerHTML.toUpperCase == array[i].name.toUpperCase ){
box1.innerHTML += array[i].name + "<br>"
}
}
或新创建的对象有什么意义？ innerHTML始终为空字符串。

try to use .value for input element.

首先，你需要清理以前的结果块：
us-east1然后你需要追加其他结果，所以用box1.innerHTML = '';
替换=
+=
