Grails在GSP站点内部使用grails var [英] Grails using grails var in GSP Site inside javascript
问题描述
例如:我有一个会话值 session.getAttribute(我的解决方案现在(在一个GSP中):
$ b$ b
<%
def js = new String(< script type = \text / javascript\>)
js + =var jsSelectedValue =+ session.getAttribute(selectedValue)+;
js + =< / script>
out<< js
%>
然后我在我的GSP中使用jQuery Stuff等的JavaScript块,我需要这个值。
有没有另外一种方法可以在纯javascript代码中使用grails变量?
第二个问题,正好相反。我选择例如在一个下拉框中,然后单击保存,然后我想要将值$(#select-box)。val()存储在来自JS-part的会话变量中。
非常感谢您的帮助。
干杯,

为什么不使用JavaScript GSP标签?解决方案可能如下所示:
< g:javascript>
var jsSelectedValue =$ {session.selectedValue};
< / g:javascript>
I have a question using grails variable values in javascript code in a GSP file.
For Example: I have a session value session.getAttribute("selectedValue") and I want to use this value inside javascript code part.
My solution is now (inside a GSP):
<%
def js = new String("<script type=\"text/javascript\">")
js += "var jsSelectedValue = " + session.getAttribute("selectedValue") + ";"
js += "</script>"
out << js
%>
and then I have javascript block inside my GSP with jQuery Stuff and so on, there I need this value.
Is there another way to have grails variables accessible inside pure javascript code?
And second question, the exactly other way around. I select for example in a dropdown box and click "save" and then i want to store the value $("#select-box").val() inside a session variable from JS-part.
Thank you very much in advance for your help.
Cheers,

Why do not use the javascript GSP-tag? A solution can look like this:
<g:javascript>
var jsSelectedValue = "${session.selectedValue}";
</g:javascript>
