我正在尝试将图像自动更新为输入框的文本。
这是索引代码:

<body>
<div id="registeer">

  <form method="post" action="javascript:login()">
    <input type="text" name="gebruikersnaam" placeholder="Gebruikersnaam" /><br><br>
    <input type="password" name="wachtwoord" placeholder="Wachtwoord" /><br><br>
    <input type="submit" value="Registeer">
  <form>
  <br>

  </div>
  <div id="registeer-avatar"></div>


<script src="registeer.js"></script>




这是registeer.js:

$("#registeer input[type=text]").keyup(function(){
var value = $(this).val();
var background = "url(https://www.habbo.nl/habbo-imaging/avatarimage?img_format=gif&user=" + value + "&action=std&direction=3&head_direction=3&gesture=sml&size=b)";
$("#registeer-avatar").css("background", background);
});


$("#registeer input[type=text]").blur(function() {
if(!this.value) {
    $("#registeer-avatar").css("background", "url(https://www.habbo.nl/habbo-imaging/avatarimage?img_format=gif&user=ulk&action=std&direction=3&head_direction=3&gesture=sml&size=b)");
}
});


因此,如果您输入第一个输入(例如“ hi”),则registeer-avatar中的图像将是habbo ....&user = hi,但无法正常工作。

谢谢您的帮助。

最佳答案

它可以工作,但是您需要调整容器的大小:

  <div id="registeer-avatar"></div>


因为它现在没有“空格”,并且在设置背景时不会显示。

尝试例如CSS:

#registeer-avatar {
    border: 1px solid #eee;
    min-height: 100px;
}




$("#registeer input[type=text]").keyup(function(){
var value = $(this).val();
var background = "url(https://www.habbo.nl/habbo-imaging/avatarimage?img_format=gif&user=" + value + "&action=std&direction=3&head_direction=3&gesture=sml&size=b)";
$("#registeer-avatar").css("background-image", background);

    console.log(background);

});


$("#registeer input[type=text]").blur(function() {
if(!this.value) {
    $("#registeer-avatar").css("background", "url(https://www.habbo.nl/habbo-imaging/avatarimage?img_format=gif&user=ulk&action=std&direction=3&head_direction=3&gesture=sml&size=b)");
}
});

#registeer-avatar {
    border: 1px solid #eee;
    min-height: 100px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="registeer">

  <form method="post" action="javascript:login()">
    <input type="text" name="gebruikersnaam" placeholder="Gebruikersnaam" /><br><br>
    <input type="password" name="wachtwoord" placeholder="Wachtwoord" /><br><br>
    <input type="submit" value="Registeer">
  <form>
  <br>

  <div id="registeer-avatar"></div>
