Question

我正在尝试将innerElement设置为用户输入的值，但它会给我错误。代码如上，请帮助

*****代码*****

var abc= document.getElementById("searchbar").innerHTML = "Singapore Polytechnic"; --instead of Singapore Polytechnic I want it to be some values that was entered by the users.--

      document.getElementById("searchbar").contentEditable = "true";

      var test = abc;

Answer 1

尝试以下方法：

<body>
   <%= link_to image_tag('logo.png'), root_path %>
</body>

function changeVal(ele){
    document.getElementById("searchbar").innerHTML = ele.value;
    }

Answer 2

我没有计划你的问题是什么，但也许你在寻找这个...

foreach($_POST["choice"] as $value_choice) {
    if ($value_choice === end($_POST["choice"]))
    {
        echo  "type = '$value_choice'";
    }
    else
    {
        echo  "type = '$value_choice' OR ";
    }
}

Answer 3

我认为这就是你要找的东西

<强>代码

<input value="variable" id="val" onchange="changeVal(this)">

<强> TS

onchange(this){
    let var  = event.target.getElementsByTagName('input').value;
}
