How to change the extraParams config of a proxy at runtime in extjs?
提问by alex
I have the following store:
我有以下商店：
var store = new Ext.data.Store({
model: 'Result',
proxy: {
type: 'ajax',
extraParams: {search_term : term},
url : 'find.pl'
},
});
How can I change the parameters with which the url is called (ex. search_term) at runtime?
如何在运行时更改调用 url 的参数（例如 search_term）？

Think about it as -
You don't callthe URL. You loadthe store.
把它想象成 -
你不调用URL。你加载商店。
Now, you can specify search_term value whenever you try to load the store using something like -
现在，每当您尝试使用以下内容加载商店时，您都可以指定 search_term 值 -
store.load({
params:{
search_term:'my runtime search term'
}
//other options like a callback function, append/add flag, etc.
});

Assuming that you want to change the parameters after defining the storevariable. It obviously will depend whether Ext.data.Storeallows the parameters to be changed. If it allows then it is as simple as:
store.proxy.extraParams.search_term = //something
假设您要在定义store变量后更改参数。这显然取决于是否Ext.data.Store允许更改参数。如果允许，那么它很简单：
store.proxy.extraParams.search_term = //something

var form = this.up('form').getForm();
var searchText = form.getValues('search_term').split("=")[1];
var resultGrid = Ext.widget('ResultGrid');
var store = resultGrid.getStore();
if (searchText != undefined && searchText != '') {
store.proxy.extraParams.bomId = searchText;
}
resultGrid.store.load();
}

store.proxy.extraParams.search_term = 'any value'; //set extraparams field
store.load() //load the store
But need to take care with IE8.. check this
