如何在jQuery中的div中獲取span標記並分配文本？

Question

我用下面，

<div id='message' style="display: none;"> 
    <span></span> 
<a href="#" class="close-notify">X</a> 
</div> 

現在我想找到DIV中的跨度和分配文本吧...

function Errormessage(txt) { 
    $("#message").fadeIn("slow"); 
    // find the span inside the div and assign a text 
    $("#message a.close-notify").click(function() { 
     $("#message").fadeOut("slow"); 
    }); 
} 

Answer 1

試試這個：

$("#message span").text("hello world!"); 

在你的代碼中看到它！

function Errormessage(txt) { 
    var m = $("#message"); 

    // set text before displaying message 
    m.children("span").text(txt); 

    // bind close listener 
    m.children("a.close-notify").click(function(){ 
     m.fadeOut("slow"); 
    }); 

    // display message 
    m.fadeIn("slow"); 
}

試試這個

$("#message span").text("hello world!"); 

function Errormessage(txt) { 
    var elem = $("#message"); 
    elem.fadeIn("slow"); 
    // find the span inside the div and assign a text 
    elem.children("span").text("your text"); 

    elem.children("a.close-notify").click(function() { 
     elem.fadeOut("slow"); 
    }); 
} 

Answer 3

$("#message > span").text("your text"); 

或

$("#message").find("span").text("your text"); 

或

$("span","#message").text("your text"); 

或

$("#message > a.close-notify").siblings('span').text("your text");

function Errormessage(txt) { 
    $("#message").fadeIn("slow"); 
    $("#message span:first").text(txt); 
    // find the span inside the div and assign a text 
    $("#message a.close-notify").click(function() { 
     $("#message").fadeOut("slow"); 
    }); 
}
