Question

我从数据库回显了结果，我已经包含了jquery扩展代码以在单击标题时扩展div，但是当前点击一个结果的标题时，所有其他echo'ed div都会扩展。

有人可以帮我制作它，以便只有点击的div扩展。谢谢你的任何帮助或建议！

这是剧本：

<script type="text/javascript">
$(document).ready(function(){
$(".expanderHead").click(function(){
    $("#expanderContent").slideToggle();
    if ($("#expanderSign").text() == "+"){
        $("#expanderSign").html("−")
    }
    else {
        $("#expanderSign").text("+")
    }
});
});
</script>

这是echo声明：

    echo "<table width='50%' style='border-bottom:1px solid #000000;'";
echo "<tr>";
echo "<td>";
echo "<div id='page-wrap'>";
echo "<div class='discounted-item freeshipping'>";

echo "<a href='./img/users/" . $row['category'] . "/" . $row['username'] . "/" . $row['filename'] . "' rel='lightbox'><img src=\"./img/users/" . $row['category'] . "/" . $row['username'] . "/" . $row['filename'] . "\" alt=\"\" width='15%' height='80%' /></a>";


echo "<div id='expanderHead'>";
echo "<div class='reasonbar'><div class='prod-title' style='width: 70%;'>" .$row['fname'] . "</div><div class='reason' style='width: 29%;'><b>". $row['firstname'] . " " . $row['surname'] ."</b></div></div>";


echo "<div id='expanderContent' style='display:none'><div class='reasonbar'><div class='prod-title1' style='width: 70%;'>" . $row['lname'] . "</div><div class='reason1' style='width: 29%;'>Category:<br /> ". $row['category'] . "</div></div></div>";

echo "<div class='reasonbar'><div class='prod-title2' style='width: 70%;'><a href='#' data-reveal-id='myModal".$count."'>Click here For more info</a></div><div class='reason2' style='width: 29%;'>Price: &pound;". $row['price'] . "</div></div>";


echo "</div>";
echo "</td>";
echo "</tr>";
echo "</td>";
echo "</tr>";
echo "</table>";

你可以尝试在里面使用$（this）来查找相对于当前点击的元素

$(document).ready(function(){    
    $(".expanderHead").click(function(){
        var $exsign = $("#expanderSign");
        $(this).find("#expanderContent").slideToggle();
        $exsign.html($exsign.text() == '+' ? '-': '+');   
        // simplify your if/else into one line using ternary operator
        // if  $exsign.text() == "+" then use "-" else "+"
    });    
});

扩展div - 只希望点击的div在php echo中扩展
