使用它作为ExtJs网格存储时如何保存JSON文件 [英] How to save JSON file when use it as ExtJs grid store
问题描述
我已经开发了使用ExtJs功能的应用程序,我应该将其存储在json文件中。
我的商店看起来像这样:
var Grid1Store = new Ext .data.JsonStore({
fields:['Something 1','Something 2','Status'],
autoLoad:true,
proxy:{
type:' ajax',
url:'resources / buildJsonStore / something.json',
reader:{
type:'json'
}
}
});
其中something.json是我的数据。问题是我想要动态添加数据到我的商店,之后保存JSON文件。我通过以下方式成功添加数据:
Grid1Store.add(data);
其中数据是一些JS数组,但是我如何将这些数据插入到我使用的JSON文件中对于STORE并保存在此之后?
提前谢谢!
为了能够更新数据,您应该将数据保存在数据库中,并具有PHP (或您的服务器端语言)输出文件 something.json
(这将是 something.php
)。 / p>
然后,您将作者
配置添加到您的代理
像
proxy:{
type:'ajax',
url:'resources / buildJsonStore / something .json',
reader:{
type:'json'
},
writer:'json'
}
您的文件 something.php
然后必须使用更改的数据更新数据库。 / p>
I have developed application which use ExtJs functionality where I should keep my store in json file.
My store looks like this:
var Grid1Store = new Ext.data.JsonStore({
fields: [ 'Something 1', 'Something 2', 'Status' ],
autoLoad: true,
proxy:{
type:'ajax',
url:'resources/buildJsonStore/something.json',
reader:{
type: 'json'
}
}
});
Where something.json is my data. The problem is that I want dynamically add data to my store and after that to save the JSON file. I add data successfully with this:
Grid1Store.add(data);
where data is some JS array, but how I can insert this data into JSON file which I have used for STORE and save it after that?
Thank you in advance!
You cannot edit files in Javascript that are fetched with HTTP.
To be able to update the data, you should save your data in a database, and have PHP (or your server side language) outputting the file something.json
(which would rather be something.php
).
Then you add a writer
configuration to your proxy
, like
proxy:{
type:'ajax',
url:'resources/buildJsonStore/something.json',
reader:{
type: 'json'
},
writer: 'json'
}
Your file something.php
will then have to update the databse with the changed data.
