[英].net c# asp.net make part of Textbox text bold
I have a .NET C#/Aspx web application in which users fill in fields and the resulting form is emailed out. 我有一个.NET C#/ Aspx Web应用程序,用户在其中填写字段,并通过电子邮件发送结果表单。 I have a requirement to allow users to highlight text and then make that text either bold or coloured or both.
我要求允许用户突出显示文本,然后将该文本设置为粗体或彩色或两者。
I have done a bit of searching on the net and found that javascript might be the best option. 我在网上做了一些搜索,发现javascript可能是最好的选择。 However, when the script inserts the html tags - it doesn't render within the textbox.I know this is a limitation of the asp.net textbox but is there anyway around this?
但是,当脚本插入html标签时 - 它不会在文本框中呈现。我知道这是asp.net文本框的限制但是无论如何都存在吗?
<script type="text/javascript">
function formatText(tag) {
var selectedText = document.selection.createRange().text;
if (selectedText != "") {
var newText = "<" + tag + ">" + selectedText + "</" + tag + ">";
document.selection.createRange().text = newText;
}
}
你需要一个像ckeditor这样的富文本编辑器。
Instead reinventing the wheel, take a look at a rich text editor, like for example TinyMCE you can strip it down, so the user only have the options like bold or italic. 而是重新发明轮子,看看富文本编辑器,例如TinyMCE,你可以将其剥离,因此用户只有粗体或斜体等选项。
