显示html& copy;的文本值输入type = text中的实体? [英] show text value of html © entity in input type=text?

问题描述

我正在从包含版权字符的json文件中加载值.它作为html实体存储在json中-©呈现©.

I'm loading a value from a json file which contains a copyright character. It's stored in the json as a html entity - © which renders ©.

Handlebars正在为我渲染文件编辑器，这种方式是:如果字符串较长，则将其变成文本区域；如果字符串较短，则将其变为文本输入框.当呈现为<textarea>时，该值将显示为其字符串版本-类似于© 2013 blah foo inc，而如果将该值写入<input type='text'>值，则浏览器会将其呈现为其等效的实体，而不显示字符串本身.我不知道如何显示实体本身的文本值，而不是其解释的形状.

Handlebars is rendering a file editor for me in such a way that if the string is long it gets made into a textarea, and if it's short then it becomes a text input box instead. When rendered to a <textarea> the value is shown as its string version - something like © 2013 blah foo inc, whereas if the value is written to a <input type='text'> value, then the browser renders it as its entity equivalent, no the string itself. I can't figure out how to make the text value of the entity itself appear, not its interpreted shape.

推荐答案

据我了解，您想将html实体名称(©)转换为输入类型text/textarea的字符(©).

As I understand that you want to convert html entity name (©) into it's character (©) in input type text/textarea.

var content = "© 2014 blah foo inc";
var copyright = $('<div>').html('&copy;').text();
var encoded = content.replace(/&copy;/g, copyright);
alert(encoded); // or $('#input_id').val(encoded);
