Javascript 可以在同一个PHP文件中传递数据吗？

我有一个按钮（有人创建了它，我需要编辑），它保存到employee.php中的

$elisting

。该按钮将转到名为

edit（）

的javascript函数<代码>$elisting代码如下：

$elisting ="";

    $queryf = "select employee.id as myid,jobtitle,info,locid,deptid,gender,dob,emid,employee$cid.name,username,dept,datejoin,location.name as loc from  employee

        left join location on location$cid.id = employee.locid 

        inner join department on department.id = employee.deptid order by username

    ";

    $resultf = pg_query($queryf); 

    $numrows = pg_numrows($resultf);

    while ($rowf = pg_fetch_array($resultf)) {

        $ct=$ct+1;

        $myid = $rowf[myid];

        $uname = $rowf[username];

        $loc1 = $rowf[loc];

        $dept = $rowf[dept];

        $date = $rowf[datejoin];

        $name = $rowf[name];

        $emid = $rowf[emid];

        $dob = $rowf[dob];

        $gender = $rowf[gender];

        $job = $rowf[jobtitle];

        $info = $rowf[info];

        $datejoin = $rowf[datejoin];

        $locid = $rowf[locid];

        $deptid = $rowf[deptid];

        $newbal = $rowf[newbal];

        $templatelist = "";

        $tempcn = 0;

        $querytemp = "select tid,ltype from leaveatemplate$cid where username='$uname' order by tid desc";

        $resulttemp = pg_query($querytemp); 

        while ($rowtemp = pg_fetch_array($resulttemp)) {

            $tempcn = $tempcn +1;

            $tid = $rowtemp[tid];

            $ltype = $rowtemp[ltype];

            if($tempcn=="1")

                $templatelist = "$ltype|$tid";

            else

                $templatelist = $templatelist.","."$ltype|$tid";

        }

$elisting=$elisting."<tr><td align=\"center\">$uname</td><td align=\"center\">$loc1</td><td align=\"center\">$dept</td>
        <td align=\"center\">$date</td>
        <td align=\"center\"><a><button class=\"btn btn-mini\"data-toggle=\"modal\"href=\"#long\"
        onClick=\"javascript:edit('$name','$uname','$emid','$dob','$gender','$job','$info','$datejoin','$locid','$deptid','$myid','$templatelist');\"><i class=\"icon-pencil\"></i></a>

$llisting ="";

    $ct=0;

    //leave code
    $ccompassionate = "3";
    $cemergency = "4";
    $cmaternity = "5";
    $cmedical = "6";
    $cannual = "2";

    //leave value
    $compassionate = 2;
    $emergency = 5;
    $maternity = 60;
    $medical = 20;

    $lapplicant = $_POST['lapplicant'];

    $querye = "select leavetype.id, leavetype.ltype, leaves.leave from leavetype,leaves where username='".$_SESSION["username"]."'";

        $resulte = pg_query($querye); 

        while ($rowe = pg_fetch_array($resulte)) {

            $ct=$ct+1;

            $lid = $rowe[id];

            $ltype = $rowe[ltype];

            $leave = $rowe[leave];  

        if ($lid == $ccompassionate) {
            $compassionate_query = pg_query("select ltotal from leave where lapplicant='".$lapplicant."' and ltype='".$ccompassionate."'");
            if (count($compassionate_query) > 0) {
                foreach ($compassionate_query as $data) {
                    $total_compassionate = $total_compassionate + $data['total'];
                    $value = $compassionate - $total_compassionate;
                }

            } else {
                $value = $compassionate;
            }
$llisting=$llisting."<tr><td align=\"center\">$ct</td><td>$ltype</td><td><input type='text' value='$lapplicant'></td><td align=\"center\">";

        $llisting=$llisting."<select name=\"temp$lid\" id=\"temp$lid\" class=\"span12\"><option value=\"0\"> - </option> $tlisting</select>";

        $llisting=$llisting."</td></tr>\n";

由于我未能尝试在

edit（）

中获取

b

，因此我需要找到在

$elisting

中获取$uname的方法，并将其发送到同一个PHP文件（employee.PHP）中的

$llisting

，代码如下：

$elisting ="";

    $queryf = "select employee.id as myid,jobtitle,info,locid,deptid,gender,dob,emid,employee$cid.name,username,dept,datejoin,location.name as loc from  employee

        left join location on location$cid.id = employee.locid 

        inner join department on department.id = employee.deptid order by username

    ";

    $resultf = pg_query($queryf); 

    $numrows = pg_numrows($resultf);

    while ($rowf = pg_fetch_array($resultf)) {

        $ct=$ct+1;

        $myid = $rowf[myid];

        $uname = $rowf[username];

        $loc1 = $rowf[loc];

        $dept = $rowf[dept];

        $date = $rowf[datejoin];

        $name = $rowf[name];

        $emid = $rowf[emid];

        $dob = $rowf[dob];

        $gender = $rowf[gender];

        $job = $rowf[jobtitle];

        $info = $rowf[info];

        $datejoin = $rowf[datejoin];

        $locid = $rowf[locid];

        $deptid = $rowf[deptid];

        $newbal = $rowf[newbal];

        $templatelist = "";

        $tempcn = 0;

        $querytemp = "select tid,ltype from leaveatemplate$cid where username='$uname' order by tid desc";

        $resulttemp = pg_query($querytemp); 

        while ($rowtemp = pg_fetch_array($resulttemp)) {

            $tempcn = $tempcn +1;

            $tid = $rowtemp[tid];

            $ltype = $rowtemp[ltype];

            if($tempcn=="1")

                $templatelist = "$ltype|$tid";

            else

                $templatelist = $templatelist.","."$ltype|$tid";

        }

$elisting=$elisting."<tr><td align=\"center\">$uname</td><td align=\"center\">$loc1</td><td align=\"center\">$dept</td>
        <td align=\"center\">$date</td>
        <td align=\"center\"><a><button class=\"btn btn-mini\"data-toggle=\"modal\"href=\"#long\"
        onClick=\"javascript:edit('$name','$uname','$emid','$dob','$gender','$job','$info','$datejoin','$locid','$deptid','$myid','$templatelist');\"><i class=\"icon-pencil\"></i></a>

$llisting ="";

    $ct=0;

    //leave code
    $ccompassionate = "3";
    $cemergency = "4";
    $cmaternity = "5";
    $cmedical = "6";
    $cannual = "2";

    //leave value
    $compassionate = 2;
    $emergency = 5;
    $maternity = 60;
    $medical = 20;

    $lapplicant = $_POST['lapplicant'];

    $querye = "select leavetype.id, leavetype.ltype, leaves.leave from leavetype,leaves where username='".$_SESSION["username"]."'";

        $resulte = pg_query($querye); 

        while ($rowe = pg_fetch_array($resulte)) {

            $ct=$ct+1;

            $lid = $rowe[id];

            $ltype = $rowe[ltype];

            $leave = $rowe[leave];  

        if ($lid == $ccompassionate) {
            $compassionate_query = pg_query("select ltotal from leave where lapplicant='".$lapplicant."' and ltype='".$ccompassionate."'");
            if (count($compassionate_query) > 0) {
                foreach ($compassionate_query as $data) {
                    $total_compassionate = $total_compassionate + $data['total'];
                    $value = $compassionate - $total_compassionate;
                }

            } else {
                $value = $compassionate;
            }
$llisting=$llisting."<tr><td align=\"center\">$ct</td><td>$ltype</td><td><input type='text' value='$lapplicant'></td><td align=\"center\">";

        $llisting=$llisting."<select name=\"temp$lid\" id=\"temp$lid\" class=\"span12\"><option value=\"0\"> - </option> $tlisting</select>";

        $llisting=$llisting."</td></tr>\n";

调用html页面的代码：

if($msg!="") $alert= "<div class=\"alert\"><i class=\"icon-info-sign\"></i> $msg</div><p>&nbsp;</p>";

    $source2 = file_get_contents('http://'.$_SESSION["url"].'/cgi-bin/vo/'.$_SESSION["sessid"].'.interface.designer.vo?file=eleave/employee.htm');

    $html2 = str_replace("[templateurl]",$templateurl,$source2);

    $html2 = str_replace("[alert]",$alert ,$html2);

    $html2 = str_replace("[elisting]",$elisting ,$html2);

    $html2 = str_replace("[ulisting]",$ulisting ,$html2);

    $html2 = str_replace("[locationlisting]",$locationlisting ,$html2);

    $html2 = str_replace("[deptlisting]",$deptlisting ,$html2);

    $html2 = str_replace("[llisting]",$llisting ,$html2);

    $html2 = str_replace("[wfid]","sid=$sid" ,$html2);

    echo $html2;

如果（$msg！=”）$alert=“$msg
”；
$source2=file\u get\u contents（'http://'.$\u SESSION[“url”]。/cgi-bin/vo/'.$\u SESSION[“sessiond”]。.interface.designer.vo？file=eleave/employee.htm'）；
$html2=str_replace（“[templateurl]”，$templateurl，$source2）；
$html2=str_replace（“[alert]”，$alert，$html2）；
$html2=str_replace（“[elisting]”，$elisting，$html2）；
$html2=str_replace（“[ulisting]”，$ulisting，$html2）；
$html2=str_replace（“[locationlisting]”，$locationlisting，$html2）；
$html2=str_replace（“[deptlisting]”，$deptlisting，$html2）；
$html2=str_replace（“[llisting]”，$llisting，$html2）；
$html2=str_replace（“[wfid]”，“[sid=$sid]”，$html2）；
echo$html2；

请先试试基本的，我对这个没问题

在JS中：

<script>
    function TestTriggered(name){
        alert("the function triggered!");
        alert("My name is: " + name);
    }
</script>

函数TestTriggered（名称）{
警报（“功能已触发！”）；
警报（“我的名字是：“+名字”）；
}

关于HTML部分

<input type="button" name="myButton" onClick="javascript:TestTriggered('John');" value="Please click"/>

请先尝试一下，看看它是如何工作的。

在你的Javascript中，只使用

函数编辑（a，b，c，d，e，f，g，h，i，j，k，l）{alert（b）；}

你得到了什么？仍然显示相同的页面，先生。。没什么变化。。我弄糊涂了。在PHP上使用print_r（）进行调试，并使用console.log（）查看您正在做什么。JS中的alert只是在同一页面上弹出一个框。如果您使用的是Chrome，请按Shift+Ctrl+J打开控制台。打开控制台，单击以触发edit（）函数，然后查看是否有任何结果。控制台没有显示任何内容，先生。这不是答案。是的，我知道，因为代码很长，它不适合注释部分。这是为了展示事情是如何运作的，然后我们可以相应地将其扩展到用户的问题。我尝试放置您的代码，它显示空白页和

NetworkError:500内部服务器错误-http://192.168.1.5/eleave/employee.php?sid=SID421464131stwptwbply497.

然后我尝试编辑我的代码：

，它显示了来自

edit（）

的相同页面，文本字段中没有数据。出现错误：

ReferenceError:testtriggered未定义。

它是否与

href=\“\35; long\”

相关？long是div的id，包含$elisting中的表单和数据。您必须首先定义函数

testtriggered

。删除

href

，因为它用于导航到其他页面我在html页面中有sir。。当我删除

href='#long'

时，控制台中没有出现任何错误<代码>引用错误：未定义testtriggered
