jQuery - 选择所有元素并删除它们的文本

Hello guys, I have spent about twenty minutes searching in vain for my answer, and need your help. There are thousands of requests for help on how to select elements with jQuery - but everyone wants to do with with some kind of condition, ie, only select an anchor with a certain ID at a certain Y position on the page.

大家好，我花了大约二十分钟徒劳地寻找答案，需要你的帮助。关于如何使用jQuery选择元素有成千上万的请求帮助 - 但是每个人都想要处理某种条件，即只在页面上的某个Y位置选择具有特定ID的锚。

I have a simple request. How do I select all <span> elements on my page and remove their text?

我有一个简单的要求。如何选择页面上的所有元素并删除其文本？

See the thing is, I have a form, and I have <spans>. When I click the Clear Button input, all fields revert back to default (of course). But I want the span elements to have their text deleted.

看到的是，我有一个表格，我有。单击“清除按钮”输入时，所有字段都将恢复为默认值（当然）。但我希望span元素删除其文本。

The <html> on it is simple:

它上面的很简单：

<input type="reset" value="Clear form" name="Clear Button" class="clear">

And my jQuery:

而我的jQuery：

/* Clear form - used to revert all Spans back to normal */
$('#Clear Button').click(function(){
        $('span').val('');

});

So, the Reset effect works because that's DOM/HTML. But my jQuery is sadly broken.

因此，重置效果起作用，因为它是DOM / HTML。但我的jQuery很遗憾。

Can anyone tell me what's going wrong? My script is after the Button declaration, if that helps.

谁能告诉我出了什么问题？我的脚本是在Button声明之后，如果有帮助的话。

Your problem is with your button selector. You are not selecting your button. Use this instead:

您的问题在于您的按钮选择器。你没有选择你的按钮。改为使用它：

/* Clear form - used to revert all Spans back to normal */
$('input[name="Clear Button"]').click(function(){
        $('span').text('');
});

Or use $('input[type="reset"]') if that's the only one there...

或者使用$（'input [type =“reset”]'）如果那是唯一一个......

Did you source the jquery.js file into your code, and make sure when your refering to the span instead of leaving it "" (blank) use the function $('span').hide Hope i helped

您是否将jquery.js文件提取到您的代码中，并确保何时引用跨度而不是留下“”（空白）使用函数$（'span'）。隐藏希望我帮助
