Jquery將文本添加到範圍

Question

<span class="field-validation-valid" data-valmsg-for="Classifications" data-valmsg-replace="true"> 
</span> 

如何向此範圍添加文本？

我試過至今如下：

var msg = $('#[data-valmsg-for="Classifications"]').val(); 
alert(msg); 

可以在此有人扔想法。

Answer 1

試試這個

$('span[data-valmsg-for="Classifications"]').text('Your Text'); //It wil add text to element 

$('span[data-valmsg-for="Classifications"]').text();//It will get your element text 

在您的文件得到這樣

var msg = $('span[data-valmsg-for="Classifications"]').text() 
alert(msg);

Answer 2

您需要使用.text()

$("[data-valmsg-for='Classifications']").text("Some Text");

Note: Above selector will add text to ANY element having a custom attribute of data-valmsg-for with a value of Classifications , so if you want to be that specific, than use span[data-valmsg-for='Classifications']
