Question

=“”

我对Jquery相当陌生（阅读：全新），尽管我已经仔细研究了Jquery上的W3School段落。似乎那里有许多未更新的问题。

但是我被困在这里：

我已经尝试过：

$('#msgN').text = 'bbb ';   
$('#msgN').val = 'bbb ';  
$('#msgN').text() = 'bbb ';   
$('#msgN').val() = 'bbb '; 
$('#msgN').text(); = 'bbb ';   
$('#msgN').val(); = 'bbb ';

当我尝试最后2个脚本时，脚本根本没有回答==错误！

我的目的是将该弹出窗口用作一般的Error Messenger弹出窗口，并根据错误条件更改msg文本。

我在做什么错了？

Answer 1

尝试

<script>
    $('#pmsg1').text('My text 1'); 
    $('#pmsg2').text('My text 2');
    $('#pmsg1').text('My text 3');
</script>

Answer 2

尝试

$('#msgN').text('bbb ');

代替

$('#msgN').text(); = 'bbb ';   
$('#msgN').val(); = 'bbb ';

Answer 3

.text()与您差不多，除了.val()和.text()是jQuery对象的方法。您不会以尝试的方式为方法分配值，而是将参数传递给它们：

$('#msgN').text('bbb ');

在“弹出窗口”中放置文本<p标签=“”
