javascript更改div文本準備就緒

Question

如何使用javascript更改文本的準備？例如ID DIV1 = YES，那麼DIV2顯示「你說YES

<div class="div1">YES</div> 
<div class="div2"></div> 

Answer 1

你寫的標識，但在你的代碼是class。

<div id=div1>YES</div> 
<div id=div2></div> 

<script> 
    var div1 = document.getElementById('div1'); 
    var div2 = document.getElementById('div2'); 

    if (div1.innerHTML == 'YES') { 
     div2.innerHTML = 'You said YES'; 
    } 
</script>

或通常，如果你想投入到第二個DIV「你說」和第一DIV的內容。

<div id=div1>XY</div> 
<div id=div2></div> 

<script> 
    var div1 = document.getElementById('div1'); 
    var div2 = document.getElementById('div2'); 

    div2.innerHTML = 'You said ' + div1.innerHTML; // returns 'You said XY' 
</script>

Answer 2

$(function(){ 
 
    var text = $('.div1').text(); 
 
    
 
    if(text == "YES") 
 
    
 
    $('.div2').text("You said yes"); 
 
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<div class="div1">YES</div> 
 
<div class="div2"></div>

Answer 3

這樣的事情，如果我的理解是否正確？

document.addEventListener('DOMContentLoaded',function(){ 
var div1 = document.getElementById('div1'); 
var div2 = document.getElementById('div2'); 
if(div1.innerText.toLowerCase() == 'yes') { 
    div2.innerHTML = 'You said YES'; 
} 
});
