Javascript 如何检查php数组值是否在js数组中？

首先，我从php数组中获取所有值：

然后我需要检查当前id值是否在js数组中，并相应地继续：

if($.inArray(this.id, savedInternal) !== -1) {
    console.log("yes");               
} else {
    console.log("no");  
}

这是在一个元素上的鼠标上发生的，如果我放置以下id是正确的，那么它与This.id无关

我得到128545，这是正确的

完整代码：

google.maps.event.addListener(circle, 'mouseover', function(e) {

  <?php
    $user_id = get_current_user_id();
    $userPostsInternal = get_user_meta( $user_id, 'save_post_internal', TRUE );
    $userPostsExternal = get_user_meta( $user_id, 'save_post_external', TRUE )
  ?>

  var savedInternal = "<?php echo $userPostsInternal; ?>";
  var savedExternal = "<?php echo $userPostsExternal; ?>";

  savedInternal = savedInternal.split(',');
  savedExternal = savedExternal.split(',');

  $("#timeSearch").removeClass("fadeIn").addClass("fadeOut");
  $(".infoBox").removeClass("fadeOut").addClass("fadeIn");
  if(this.currSite == "curr" ) {
    var linkGo = this.linkToPost;
    var whatSite = this.currSite;
    if($.inArray(this.id, savedInternal) !== -1) {
      var contentString = '<div class="row infoBox"><div class="col"><p>' + this.site + '</p><hr><h5>'+this.title+'</h5><hr><p><button data-whatSite="'+whatSite+'" data-id="'+this.id+'" type="button" class="btn-site btn btn btn-outline-dark btn-block">Già nella box</button></p><hr><a class="d-block margin-top-20 btn btn-outline-dark btn-block" href="'+linkGo+'">Vedi contenuto</a></div></div>';                  
    } else {
      var contentString = '<div class="row infoBox"><div class="col"><p>' + this.site + '</p><hr><h5>'+this.title+'</h5><hr><p><button data-whatSite="'+whatSite+'" data-id="'+this.id+'" type="button" class="btn-site btn btn btn-dark btn-block">Salva nella box</button></p><hr><a class="d-block margin-top-20 btn btn-outline-dark btn-block" href="'+linkGo+'">Vedi contenuto</a></div></div>';                  
    }
  } else { 
    var linkGo = linkExternal+this.linkToPost;
    var whatSite = this.currSite;
    if($.inArray(this.id, savedExternal) !== -1) {
      var contentString = '<div class="row infoBox"><div class="col"><p>' + this.site + '</p><hr><h5>'+this.title+'</h5><hr><p><button data-whatSite="'+whatSite+'" data-id="'+this.id+'" type="button" class="btn-site btn btn btn-outline-dark btn-block">Già nella box</button></p><hr><a class="d-block margin-top-20 btn btn-outline-dark btn-block" href="'+linkGo+'">Vedi contenuto</a></div></div>';                  
    } else {
      var contentString = '<div class="row infoBox"><div class="col"><p>' + this.site + '</p><hr><h5>'+this.title+'</h5><hr><p><button data-whatSite="'+whatSite+'" data-id="'+this.id+'" type="button" class="btn-site btn btn btn-dark btn-block">Salva nella box</button></p><hr><a class="d-block margin-top-20 btn btn-outline-dark btn-block" href="'+linkGo+'">Vedi contenuto</a></div></div>';                  
    }
  }
  infoWindow = new google.maps.InfoWindow({content: contentString});
  infoWindow.setPosition(this.getCenter());
  infoWindow.open(map);
  btnBoxSave(infoWindow, whatSite);
});

使用严格的比较。 从您发布的代码来看，数组似乎包含使用.split创建的字符串。。。它返回一个字符串数组和您正在检查的值，以查看该值是否在数组中。this.id是一个数字

要解决此问题，请使用：

---

$.inaraythis.id.toString、savedInternal和$.inaraythis.id.toString、savedInternal

$。inaray使用严格的比较，确保this.id与数组中的值的类型相同。@Titus看起来我无法在gmap中鼠标悬停时访问js数组，就像我访问console.logsavedInternal一样；如果我将整个数组位放在gmap中悬停状态之前，我将得到正确的值$userPostsInternal和$userpostseternal是php数组？试试：$.inaraythis.id.toString，savedInternal，对另一个检查也做同样的操作。@FrançoisHuppéyes indeed很多，完全有意义

if($.inArray(this.id, savedInternal) !== -1) {
    console.log("yes");               
} else {
    console.log("no");  
}

console.log(this.id);

google.maps.event.addListener(circle, 'mouseover', function(e) {

  <?php
    $user_id = get_current_user_id();
    $userPostsInternal = get_user_meta( $user_id, 'save_post_internal', TRUE );
    $userPostsExternal = get_user_meta( $user_id, 'save_post_external', TRUE )
  ?>

  var savedInternal = "<?php echo $userPostsInternal; ?>";
  var savedExternal = "<?php echo $userPostsExternal; ?>";

  savedInternal = savedInternal.split(',');
  savedExternal = savedExternal.split(',');

  $("#timeSearch").removeClass("fadeIn").addClass("fadeOut");
  $(".infoBox").removeClass("fadeOut").addClass("fadeIn");
  if(this.currSite == "curr" ) {
    var linkGo = this.linkToPost;
    var whatSite = this.currSite;
    if($.inArray(this.id, savedInternal) !== -1) {
      var contentString = '<div class="row infoBox"><div class="col"><p>' + this.site + '</p><hr><h5>'+this.title+'</h5><hr><p><button data-whatSite="'+whatSite+'" data-id="'+this.id+'" type="button" class="btn-site btn btn btn-outline-dark btn-block">Già nella box</button></p><hr><a class="d-block margin-top-20 btn btn-outline-dark btn-block" href="'+linkGo+'">Vedi contenuto</a></div></div>';                  
    } else {
      var contentString = '<div class="row infoBox"><div class="col"><p>' + this.site + '</p><hr><h5>'+this.title+'</h5><hr><p><button data-whatSite="'+whatSite+'" data-id="'+this.id+'" type="button" class="btn-site btn btn btn-dark btn-block">Salva nella box</button></p><hr><a class="d-block margin-top-20 btn btn-outline-dark btn-block" href="'+linkGo+'">Vedi contenuto</a></div></div>';                  
    }
  } else { 
    var linkGo = linkExternal+this.linkToPost;
    var whatSite = this.currSite;
    if($.inArray(this.id, savedExternal) !== -1) {
