Vue calls Android and IOS methods

Alert doesn't work in ios, I don't know why, so I wrote a pop-up box, okaymethods: {
     _IsIOS(){ // Check if it is aN iPhone
            if (/(iPhone|iPad|iPod|iOS)/i.test(window.navigator.userAgent)) {
		        return true;
		    } else {
		        return false; }},_IsAndroid(){ // Check whether it is Android
            if (/(Android|Adr)/i.test(window.navigator.userAgent)) {
		        return true;
		    } else {
		        return false; }},share(){ // Click the button method
            if (this._IsIOS()) {
                try{
                    // WebKit is available in ios
                    // listen for the share function in ios
                    // If you want to set the parameters, you can't listen to them
                    window.webkit.messageHandlers.share.postMessage("11111");
                }catch(err){
                    this.$toast({text: "Call exception"}); // This is the popbox function I wrapped myself
                    return; }}else if (this._IsAndroid()) {
                try{
                    // Define the share function in Android
                    window.share.share("11111");
                }catch(err){
                    this.$toast({text: "Call exception"}); // This is the popbox function I wrapped myself
                    return; }}}}Copy the code
