javascript - 在grails gsp标签中输入jquery语句

Question

当我尝试在 grails 中使用 jQuery 句子时，出现多重编译错误 <g:link>标签

var ul = $("#authorList > ul");
ul.append('<li><g:link action="show" controller="author" id="'+$('#authorID').val()+'">+'+$('#authorField').val()+'</g:link></li>')

我只在 id=""属性内的 jquery 中遇到错误，这样

ul.append('<li><g:link action="show" controller="author" id="">+'+$('#authorField').val()+'</g:link></li>')

该页面正在运行，但我无法获取动态链接，它的语法如何正确？

grails-app\views\book_form.gsp 第 35 行左右

function appendAuthor(ev) {
34:        var ul = $("#authorList > ul");
35:        ul.append('<li><g:link action="show" controller="author" id="'+$('#authorID').val()'">+'+$('#authorField').val()+'</g:link></li>')
36:    }

我不知道GSP，但一般ID不能以数字开头。

"Using characters except ASCII letters, digits, '_', '-' and '.' may cause compatibility problems, as they weren't allowed in HTML 4. Though this restriction has been lifted in HTML 5, an ID should start with a letter for compatibility."

如果你只使用 DOM getElementById () 方法而不是 jQuery 不是更好

ul.append('<li><g:link action="show" controller="author" id="sth_'+document.getElementById('authorID').value+'">+'+document.getElementById('authorID').value+'</g:link></li>')
