| abilityName | Read only | string | No | Name of the ability. If both **package** and **abilityName** are specified in a **Want** object, the **Want** object can match a specific ability. The value of **abilityName** must be unique in an application.|
| uri | Read only | string | No | URI information to match. If **uri** is specified in a **Want** object, the **Want** object will match the specified URI information, including **scheme**, **schemeSpecificPart**, **authority**, and **path**.|
| type | Read only | string | No | MIME type, for example, **text/plain** or **image/***. |
| flags | Read only | number | No | How the **Want** object will be handled. By default, numbers are passed in. For details, see [flags](js-apis-featureAbility.md#flags).|

**Example**
``` js
var want = {
"deviceId": "", // An empty deviceId indicates the local device.
"bundleName": "com.extreme.test",
"abilityName": "MainAbility",
"moduleName": "entry" // moduleName is optional.
};
this.context.startAbility(want, (error) => {
// Start an ability explicitly. The bundleName, abilityName, and moduleName parameters uniquely identify an ability.
console.log("error.code = " + error.code)
})
```
- Basic usage
``` js
var want = {
"deviceId": "", // An empty deviceId indicates the local device.
"bundleName": "com.extreme.test",
"abilityName": "MainAbility",
"moduleName": "entry" // moduleName is optional.
};
this.context.startAbility(want, (error) => {
// Start an ability explicitly. The bundleName, abilityName, and moduleName parameters work together to uniquely identify an ability.
console.log("error.code = " + error.code)
})
```
- Passing a file descriptor (FD)
``` js
var fd;
try {
fd = fileio.openSync("/data/storage/el2/base/haps/pic.png");
} catch(e) {
console.log("openSync fail:" + JSON.stringify(e));
}
var want = {
"deviceId": "", // An empty deviceId indicates the local device.
"bundleName": "com.extreme.test",
"abilityName": "MainAbility",
"moduleName": "entry" // moduleName is optional.
"parameters": {
"keyFd":{"type":"FD", "value":fd}
}
};
this.context.startAbility(want, (error) => {
// Start an ability explicitly. The bundleName, abilityName, and moduleName parameters work together to uniquely identify an ability.
console.log("error.code = " + error.code)
})
```
- Passing **RemoteObject** data
``` js
class Stub extends rpc.RemoteObject {
constructor(des) {
if (typeof des == 'string') {
super(des);
} else {
return null;
}
}
onRemoteRequest(code, data, reply, option) {
if (code === 1) {
console.log('onRemoteRequest called')
let token = data.readInterfaceToken();
let num = data.readInt();
this.method();
return true;
}
return false;
}
method() {
console.log('method called');
}
}
var remoteObject = new Stub('want-test');
var want = {
"deviceId": "", // An empty deviceId indicates the local device.
"bundleName": "com.extreme.test",
"abilityName": "MainAbility",
"moduleName": "entry" // moduleName is optional.
"parameters": {
"keyRemoteObject":{"type":"RemoteObject", "value":remoteObject}
}
};
this.context.startAbility(want, (error) => {
// Start an ability explicitly. The bundleName, abilityName, and moduleName parameters work together to uniquely identify an ability.
console.log("error.code = " + error.code)
})
```
