php - 这个javascript和php代码有什么问题

我一直在调试一个小时：

<script type="text/javascript">
function initialize() {
    alert('test');
    var latlngarr = new Array();
    var titlearr = new Array();
    <?php
        echo "latlngarr.length=".$response->total.";";
        echo "titlearr.length=".$response->total.";";
        for ($i=0;$i<$response->total;$i++){
            echo "latlngarr[".$i."] = new google.maps.LatLng(".$response->businesses[$i]->location->coordinate->latitude.",".$response->businesses[$i]->location->coordinate->longitude.");";
            echo "titlearr[".$i."] = \"".$response->businesses[$i]->name."\";";
        }
    ?>

    var myOptions = {
        zoom: 10,
        center: latlngarr[0],
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
    var markerarr = new Array(titlearr.length);
    for(var i=0;i<markerarr.length;i++)
        markerarr[i] = new google.maps.Marker({position: latlngarr[i], map: map, title:titlearr[i]});

}
</script>

<body onload="initialize()">

我得到的错误是：

未捕获到的SyntaxError：意外令牌<

和

未捕获的ReferenceError：未定义初始化

当我删除该PHP代码块时，它不会给我该错误。为什么？

更新：

错误在这里：

$(".saved").live('click', function() {
    var $btn = $(this);
    $.post("update.php", {uid: my_uid, save: "no", mid: "<?php echo $mid; ?>"}, function(){
        setTimeout(function(){
            $btn.replaceWith('<a class="save action_btn" onclick="return false;">Save</a>');
        }, 100); //this is line 76
    });
});

这是从该初始化函数生成的JS：

function initialize() {
    alert('test');
    var latlngarr = new Array();
    var titlearr = new Array();

最佳答案

好吧，<br />不是JavaScript，所以会导致错误。

其余的html也会在javascript块内回显...

如您所见，它基本上是一条很大的错误消息，来自php。
