如何更改ExtJS商店代理中extraParams的分隔符？

Question

I'm stuck with a problem related to the extraParams of an ExtJS store.. I need to change the default params separator & to a customized ; since the web service I'm accessing doesn't respond to &.

Is there a way to change the separator?

Bests, Andreas

Answer 1

There's nothing built in to ExtJS to allow customisation of the parameter separator - the use of '&' is a de-facto standard, after all.

However, you can change the default behaviour if you need to by overriding Ext.Object.toQueryString

Ext.define('Ext.override.CustomQueryString', {
  override: 'Ext.Object',
  toQueryString: function() {
    var queryString = this.callParent(arguments);
    return queryString.replace('&', ':');
  }
})

Something like that would change behaviour globally. This may or may not be a good thing to do.

Answer 2

I found a workaround on the Sencha forums:

yourStore.proxy.url = 'your/url/' + yourParameter + ';.....';

With this line, before loading the store, it's possible to go around the extraParams and still pass them directly to the used proxy using the url field.
