Javascript 无法读取数组,javascript,Javascript,嘿，我试图制作一个阵列，读取所有内容，然后用用户提供的内容进行检查，但情况是这样的，当我选择“ATI Radeon HD 2600 Overview”时，它可以工作，但当我选择“ATI Radeon X1950 Series”或之后的任何内容时，它不工作，它只会挂起整个系统。下面是代码 function setValue() { myVariable = document.forms["myform"]["gname"].value; myVariable2 = document

这是因为循环变量

，在每个

循环中，您需要使用不同的循环变量，如

i、j、k、l

等。。。差不多
