Question

我有一个问题我想将注册商标符号附加一个按钮，我想用jquery完成它，因为有很多很多按钮需要符号，当我用html例如（下面）它奏效了。

<input type="button" class="button_a" value="Value &reg;" />

但是当我使用如下的jquery时，它返回纯文本：

$('.button_a').each(function(){
    $(this).attr("value",$(this).attr("value")+" &reg;");
});

我不想浪费我的时间和空间，将®放在所有按钮的值中，所以我希望它在jquery中完成，但我做错了什么。

我知道这是一个迟缓的问题，但请有人在这个问题上帮助我

也可以使用Javascript。

如需了解更多信息，请发表评论并询问

...谢谢

Answer 1

®呈现为文本字符串，但您可以使用unicode \u00AE

$('.button_a').each(function(){
    this.value = this.value +" \u00AE";
});

或只是®：

$('.button_a').each(function(){
    this.value = this.value +" ®";
});

Answer 2

因为，虽然您正在操作的DOM是从HTML文档初始化的，但您现在正在处理DOM而不是HTML。您将值写为文本而不是HTML。

您需要使用文字字符（"®"）或JavaScript转义序列（"\u00AE"）。

encode

$('.button_a').each(function () { $(this).val("value " + $("<div/>").html('®').text()); });将返回编码值。

演示：here

Answer 4

您需要按BIO* bioRaw; std::unique_ptr<BIO, decltype(&BIO_free)> bio(bioRaw, BIO_free);处理内容，因为html实体由html()函数操作，请尝试此代码。

html()

Answer 5

使用隐藏的div。

$('.button_a').each(function(){
    var decoded = $('<div/>').html('&reg;').text();
    $(this).val($(this).val() + ' ' + decoded);
});

参见 Sample

Answer 6

在你的情况下，普通的js更直接：

$('.button_a').each(function(){
    this.value += " &reg;";
});

- 编辑 - 不幸的是，这仍然是逃脱的，实际上你需要

    this.value += " \u00AE";
