Grails GSP在脚本中访问变量 [英] Grails GSP accessing variables within script
问题描述
我已经搜索了这个，但似乎无法找到正确的解决方案。我会贬低这一点，看看我错了。
我正在使用Grails作为项目，我非常喜欢它。我认为这是很难解决的是在GSP的。
有人可以告诉我给：
控制器：
def index（）
{
def message =这是一个测试
[message：message]
}
view
<！DOCTYPE html>
< html lang =en>
< head>
< script type =text / javascript>
$（document）.ready（function（）{
如何访问变量
}）;
< body>< / body>
< / html>
我试图提供一些第三方JavaScript库，并且遇到了一个难题。是的，我可以手动ajax或使用第三方库来调用ajax thingy。但是，我认为这是一个Grails的方式，所以我不必做太多繁重的工作。我的意思是说，你是否有机会在脚本上面访问它，并使所有的东西全球化？
我使用的示例库是 JQwidgets 库，它确实有ajax调用，但我宁愿将数组等通过Grails中的命名操作直接传递给它。
可以这样写：
<！DOCTYPE html>
< html lang =en>
< head>
< script type =text / javascript>
$（document）.ready（function（）{
var message =$ {message};
console.log（我来自GSP，message）;
$（input [selector]）。val（message）; //只是一个哑例子
}）;
< / script>
< / head>
< body>
< / body>
< / html>
I have searched for this but cannot seem to find the right solution. I am going to dumb down this a bit and see where I am going wrong.
I am using Grails for a project and I am really enjoying it. Where I think it is hard to get around is in the GSP's.
Can someone tell me given:
Controller:
def index()
{
def message = "This is a test"
[message: message]
}
Within the view
<!DOCTYPE html>
<html lang="en">
<head>
<script type="text/javascript">
$(document).ready(function() {
HOW DO YOU ACCESS THAT VARIABLE IN HERE
});
<body></body>
</html>
I am trying to feed some 3rd party javascript libs and I am having an issue trying to figure this out. Yes, I can manually ajax it or use the 3rd party library to call an ajax thingy. However, I thought there was a grails way for this so that I do not have to do so much heavy lifting. I mean are you pros out there accessing it above the script {} and making all things global? Just trying to figure out what the correct way of doing this is.
Example library I am using is the JQwidgets library which does have ajax calls, but I would rather pass in arrays and such directly into via named actions in Grails.
You can write like this:
<!DOCTYPE html>
<html lang="en">
<head>
<script type="text/javascript">
$(document).ready(function() {
var message = "${message}";
console.log("I'm from GSP", message);
$("input[selector]").val(message); // Just a dumb example
});
</script>
</head>
<body>
</body>
</html>
