我在PHP数组中有一个JSON字符串数组。我想将此数组转换为JavaScript数组，以便将每个数组索引视为Object并访问其信息。
我遇到的问题是，当我对数组执行json_encode函数以使其对JS可读时，它会在“”引号之前添加反斜杠，使其成为无效的JSON。
我尝试使用JSON_UNESCAPED_SLASHES，但它不会在引号前删除反斜杠。
<?php
$markerArray = getMarkers();
$allMarkers = array();
for($x=0; $x<sizeof($markerArray); $x++)
{
array_push($allMarkers,$markerArray[$x]['json']);
}
$allMarkersJson = json_encode($allMarkers, JSON_UNESCAPED_SLASHES);
?>
<script>
var allMarkers = <?php echo $allMarkersJson ?>;
</script>
我觉得奇怪的是，如果我这样做：
console.log(allMarkers[0]);
控制台将显示一个有效的JSON格式字符串，但是当我尝试使用以下内容访问JSON的信息时：
var firstLocation = allMarkers[0].geometry.location //this line doesnt work
我查看了网页上的来源，我的JSON字符串数组如下所示：
var allMarkers =

var map = allMarkers.map(function(e) {
return JSON.parse(e);
});
console.log(map);
答案 1 :(得分：0)
注意allMarkers如何包含J ["和"]。这意味着它将内容视为ARRAY，其中包含SINGLE STRING。该字符串是转义的JSON字符串。
这就是你这样做的原因：
var firstIndex = allMarkers[0];
console.log(firstIndex);
你得到它没有斜杠：它抓住第一个元素（即[0]位），然后将其打印为字符串，而不是作为JSON对象。
尝试更改
$allMarkersJson = json_encode($allMarkers, JSON_UNESCAPED_SLASHES);
到
$allMarkersJson = json_encode($allMarkers);
如果您正在尝试保留数组概念，那么使用单引号可能会有效，但无法查看getMarkers函数，因此我们可以看到此值给出的内容，我们无法确定： $markerArray[$x]['json']
