-- 用于监听输入框事件的示例脚本

const { ccclass, property } = cc._decorator;

@ccclass
class YourComponent extends cc.Component {

    @property(cc.EditBox)
    yourEditBox: cc.EditBox = null;

    onLoad() {
        // 监听输入框的输入事件
        this.yourEditBox.node.on('editing-did-began', this.onEditingDidBegan, this);
        this.yourEditBox.node.on('text-changed', this.onTextChanged, this);
        this.yourEditBox.node.on('editing-did-ended', this.onEditingDidEnded, this);
    }

    onEditingDidBegan() {
        cc.log('用户开始输入');
    }

    onTextChanged() {
        cc.log('用户输入内容发生变化', this.yourEditBox.string);
    }

    onEditingDidEnded() {
        cc.log('用户结束输入');
    }
}
