eval函数与showModalDialog的结合使用

function doddkm()
{
    var ran = Math.random();
    var loan_id = document.all.LOAN_ID.value;
    var arr = window.showModalDialog("..src");
    if ( arr != null && arr.length > 0){
        document.all.LOAN_ID.value = arr[0];

    }
}

在子窗口操作，返回一个array，写出这样也可以

function doddkm()
{
    var ran = Math.random();
    var loan_id = document.all.LOAN_ID.value;
    var arr = eval(window.showModalDialog("..scr "));
    if ( arr != null && arr.length > 0){
        document.all.LOAN_ID.value = arr[0];

    }
}
