我正在使用Node.js的表单库(表单),这将为后台呈现一个表单所以:
I am using the Forms library for Node.js (Forms), which will render a form for me on the backend as so:
var signup_form = forms.create({ username: fields.string({required: true}) , password: fields.password({required: true}) , confirm: fields.password({ required: true , validators: [validators.matchField('password')] }) , email: fields.email() }); var signup_form_as_html = signup_form.toHTML();最后一行 var signup_var signup_form_as_html = signup_form.toHTML(); 创建一个如下所示的HTML块:
The final line var signup_var signup_form_as_html = signup_form.toHTML(); creates a block of HTML which looks as such:
<div class="field required"><label for="id_username">Username</label><input type="text" name="username" id="id_username" /></div><div class="field required"><label for="id_password">Password</label><input type="password" name="password" id="id_password" /></div><div class="field required"><label for="id_confirm">Confirm</label><input type="password" name="confirm" id="id_confirm" /></div><div class="field"><label for="id_email">Email</label><input type="text" name="email" id="id_email" /></div>基本上只是一长串HTML。然后我尝试使用EJS和Express使用以下代码来呈现它:
Basically just a long string of HTML. I then try to render it using EJS and Express using the following code:
res.render('signup.ejs', { session: loginStatus(req) , form: signup_form_as_html });但是,渲染HTML只是我上面发布的字符串,而不是实际的HTML一个我想要的表格)。有没有办法使该字符串使用EJS呈现为实际的HTML?或者我必须使用像玉的东西?
But on rendering the HTML is simply the string that I posted above, rather than actual HTML (and thus a form as I want). Is there any way to make that string render as actual HTML using EJS? Or will I have to use something like Jade?
推荐答案使用ejs可以使用
<% code %>...这是被评估但未打印出来的代码。
... which is code that is evaluated but not printed out.
<%= code %>...这是被评估和打印(转义)的代码。
... which is code that is evaluated and printed out (escaped).
<%- code %>...这是被评估和打印输出(不转义)的代码。
... which is code that is evaluated and printed out (not escaped).
由于你想打印你的变量而不能将其转义,你的代码将是最后一个类型(使用 - <% )。在你的情况下:
Since you want to print your variable and NOT escape it, your code would be the last type (with the -<%). In your case:
<%- my_form_content %>有关更多信息,请参阅完整的ejs文档
