<p>Because the line of code <code>$('#myinput').val(name)</code> is jquery syntax.</p>

<p>You can change it to javascript by</p>

<pre><code>document.getElementById('myinput').value = name;

<p>it is equal with <code>$('#myinput').val(name);</code></p>

<pre><code>$('myinput').val(name);
</code></pre>

<p>is for jquery only. if you don't want to use jquery then use this</p>

<pre><code>document.getElementById('myinput').value = name;
</code></pre>

<p>for a pure javascript..</p>

<p>Here is my answer for this.</p>

<pre><code>&lt;input id="myinput"/&gt;

&lt;script type="text/javascript"&gt;
    function getName() {
    do {
        var name=prompt("Please enter your CLAM username");
    }
    while(name.length &lt; 4);
    document.getElementById('myinput').value = name;
}
getName();
    &lt;/script&gt;
</code></pre>

<p>note: don't put your <code>&lt;input id="myinput"/&gt;</code> at the bottom or else you will get null. put it above the script.</p>


<p>I'm planning to create a JavaScript prompt where you can enter your name and it will go to the 's value. How can I make the code work? I tried the below code but it seems it needed a jQuery 1.7.1 </p>

<pre><code>function getName() {
    do {
        var name=prompt("Please enter your CLAM username");
    }
    while(name.length &lt; 4);
    $('#myinput').val(name);
}

getName();
</code></pre>

<p>HTML</p>

<pre><code>&lt;input id="myinput"/&gt;
</code></pre>

<p>I expect the output to be <code>&lt;input id="myinput" value"name from prompt"&gt;</code></p>


Prompt to enter name into input

jQuery

我计划创建一个JavaScript提示符，您可以在其中输入您的姓名，它将转到的值。我如何才能使代码工作?我尝试了以下代码，但它似乎需要jQuery 1.7.1function getName() {    do {        var name=prompt("Please enter your CLAM usern...
