How to call two function on onpress event in react native?
In below code, I want to call both methods on onpress
event but I'm facing some issues, please give some idea how to call two methods on onpress event.
One method for start chatting and second for changing images on onpress event. Thank you
chatStart = () => {
var { msg } = this.state;
var { o_code } = this.state;
var ucod = o_code;
//console.log(o_code);
var { session } = this.state;
//console.log(session);
var { ocod } = this.state;
//console.log(ocod);
var { Name } = this.state;
var user_name = Name;
var request = new XMLHttpRequest();
request.onreadystatechange = e => {
if (request.readyState !== 4) {
return;
}
if (request.status === 200) {
console.log("success", request.responseText);
} else {
console.warn("error");
}
};
// var msg = "good things take some time";
console.log(user_name);
request.open(
"POST",
"http://www.aonde.biz/mobile/getChat.php?ocod=" +
ocod +
"&ucod=" +
ucod +
"&session=" +
session,
true
);
request.setRequestHeader(
"Content-type",
"application/x-www-form-urlencoded"
);
request.send("message=" + msg + "&name=" + user_name + "&ocod=" + ocod);
};
changeImage = () => {
console.log("state changed!");
this.setState({
uri: require("./35-reject-red.png")
});
};
<View>
<TouchableOpacity activeOpacity={0.5} onPress={this.changeImage}>
<Image source={this.state.uri} />
</TouchableOpacity>

To call multiple functions on onPress, separate the calls with semicolons, like:
onPress{() => { this.functionOne(); this.functionTwo(); }

Merge two functions that you want to call in one function and give name like 'onPressBlaBlaButton'. And in the render method call this function.
