從輸入ID更改文本

Question

我試圖改變任何現有的文本與任何輸入中鍵入。我嘗試從id =「text」中取出它，但它不起作用，只顯示文本。

<input type="text" class="form-control" id="text" placeholder="Type your text here....."> 

<div class="form-group"> 
    <button>submit</button> 
</div> 
<div class="form-group" id="response"> 
    <pre>Type some text in the above text field, then log the text out here on button click</pre> 
</div> 


<script> 
    $('button').click(function() { 
     $("#response").text("#text"); 
    }); 
</script> 

Answer 1

截至目前，你只是通過字符串#text因此它顯示。使用.val()從input獲取值，然後進行設置。

$("#response").text($("#text").val()); 

Answer 2

$('button').click(function() { 
 
    
 
    $("#response").text($("#text").val()); 
 
    
 
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script> 
 
<input type="text" class="form-control" id="text" placeholder="Type your text here.....">   
 

 
    <div class="form-group"> 
 
    <button>submit</button> 
 
    </div> 
 
    <div class="form-group" id="response"> 
 
    <pre>Type some text in the above text field, then log the text out here on button click</pre> 
 
    </div> 
 

 

 

 
<script> 
 
    
 
</script>

Answer 3

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<input type="text" class="form-control" id="text" placeholder="Type your text here.....">   
 

 
    <div class="form-group"> 
 
    <button>submit</button> 
 
    </div> 
 
    <div class="form-group" id="response"> 
 
    <pre>Type some text in the above text field, then log the text out here on button click</pre> 
 
    </div> 
 

 

 

 
<script> 
 
    $('button').click(function() { 
 
    $("#response").text($("#text").val()); 
 
}); 
 
</script>

使用$("#text").val()從輸入
