深夜发帖，有点灵异
Hello，

function chk_commit_query(table_name,reg_id_base, reg_id_cmp, csv_file){

    if(chk_items.length === 0){

        alert('no items selected! And select all items in default!');

        chk_sql_base = 'select * from ' + table_name + ' where Regression_Id = ' + reg_id_base;

        chk_sql_cmp  = 'select * from ' + table_name + ' where Regression_Id = ' + reg_id_cmp;

    }

    else{

        chk_sql_base = 'select TestCase, Design_name, ';

        chk_sql_cmp  = 'select TestCase, Design_name, ';

        for (var i=0;i
            chk_sql_base += chk_items[i] + ', '

            chk_sql_cmp  += chk_items[i] + ', '

        }

        chk_sql_base += chk_items[i] + ' from ' + table_name + ' where Regression_Id = ' + reg_id_base;

        chk_sql_cmp  += chk_items[i] + ' from ' + table_name + ' where Regression_Id = ' + reg_id_cmp;

    }

    xmlHttp=GetXmlHttpObject()

    if (xmlHttp==null)

    {

        return

    }

    var url="show_cmp_internal_chk_table.php"

    url=url+"?sql_chk_cmp1 ="+chk_sql_cmp;

    url=url+"&sql_chk_base="+chk_sql_base;

    url=url+"&csv_file="+csv_file;

    url=url+"&sid="+Math.random()

    alert(url);

//此处得到的数据为：
引用
show_cmp_internal_chk_table.php?sql_chk_cmp1 =select TestCase, Design_name, Succeed, Syn from ACE_CHK_FLOW where Regression_Id = 585&sql_chk_base=select TestCase, Design_name, Succeed, Syn from ACE_CHK_FLOW where Regression_Id = 592&csv_file=ACE_20130128-0150_VS_20130130-0150_Regression_QOR_dif_2013_02_03&sid=0.5060912349899407


    xmlHttp.onreadystatechange=chk_stateChanged 

    xmlHttp.open("GET",url,true)

    xmlHttp.send(null)

}

show_cmp_internal_chk_table.php：

$csv_data4 = Array();

$sql_chk_cmp  = $_GET["sql_chk_cmp1"];

$sql_chk_base = $_GET["sql_chk_base"];

echo $sql_chk_base."
";

echo $sql_chk_cmp."
";

...

这里$sql_chk_base有数据，$sql_chk_cmp无论如何却为空，看url的信息也是有这个数据的，这是什么事情啊。这样的ajax代码用的少说也得数百次了。

------解决方案--------------------
莫非url参数后面多了个空格？
