打字稿：

@H_221_26@makeratingCall(userrating) { var score = userrating; var film_edition_id = "123456789"; var computer_name = Configurationservice.getUserData().user_username; var api_key = "key"; return new Promise( function (resolve,reject) { let xhr = new XMLhttp request(); xhr.open("POST","my-url" + this.formatParams({film_edition_id,score,computer_name,api_key }),truE); xhr.setrequestHeader("Accept","application/json"); xhr.onload = function() { if (xhr.readyState === 4 && xhr.status === 200) { resolve(JSON.parse(xhr.responseText).err_codE); } else { reject(xhr.responseText); } } xhr.onerror = function( err ) { reject ( err ); } xhr.send(); }); } formatParams = function ( params ){ return "?" + Object.keys(params).map((key) => { return `${key}=${encodeURIComponent(params[key])}` }).join("&") } rateIt() { var translate = this.translateservice; this.makeratingCall( this.currentrating ) .then(function ( err_code ) { if (err_code == 0) { dialogs.alert({ title: translate.instant("Vote_succesSFUL"),message: translate.instant("Vote_succesSFUL_MSG"),okButtontext: translate.instant("OK") }); this.rateInteraction = false; } else if (err_code == 1) { dialogs.alert({ title: translate.instant("ALREADY_VoteD"),message: translate.instant("ALREADY_VoteD_MSG"),okButtontext: translate.instant("OK") }); } else { dialogs.alert({ title: translate.instant("Vote_Failed"),message: translate.instant("Vote_Failed_MSG"),okButtontext: translate.instant("OK") }); } } ) .catch(function ( err ) { dialogs.alert({ title: translate.instant("Vote_Failed"),okButtontext: translate.instant("OK") }); }); }

HTML：

<GridLayout columns="*4,*,*" rows="*">
            <Button col="0" row="0" [text]="'SEND_rating'|translate" class="send-rating-button" (onTap)="rateIt()"
            [isUserInteractionEnabled]="rateInteraction"></Button>
            <Image src="{{ user_rating_imageurls[0] }}" col="1" row="0" class="star-image" (onTap)="rateFromUser('1')"
                [isUserInteractionEnabled]="rateInteraction"></Image>
            <Image src="{{ user_rating_imageurls[1] }}" col="2" row="0" class="star-image" (onTap)="rateFromUser('2')"
                [isUserInteractionEnabled]="rateInteraction"></Image>
            <Image src="{{ user_rating_imageurls[2] }}" col="3" row="0" class="star-image" (onTap)="rateFromUser('3')"
                [isUserInteractionEnabled]="rateInteraction"></Image>
            <Image src="{{ user_rating_imageurls[3] }}" col="4" row="0" class="star-image" (onTap)="rateFromUser('4')"
                [isUserInteractionEnabled]="rateInteraction"></Image>
            <Image src="{{ user_rating_imageurls[4] }}" col="5" row="0" class="star-image" (onTap)="rateFromUser('5')"
                [isUserInteractionEnabled]="rateInteraction"></Image>
        </GridLayout>

CSS：

.send-rating-button {
    margin-top: 10;
    margin-left: 30;
    margin-right: 10;
    margin-bottom: 10;
    BACkground-color: yellow;
}

.star-image {
    width: 30;
    margin: 10;
}

我不知道如何处理这个错误,有没有人给我一个暗示？：d
