Question

我用非常简单的代码遇到了麻烦：

property var pagesAllModels: {
    ru: [
        { title: qsTr("New"),           url: "http://bash.im"           },
        { title: qsTr("Random"),        url: "http://bash.im/random"    },
        { title: qsTr("Best"),          url: "http://bash.im/best"      },
        { title: qsTr("By rating"),     url: "http://bash.im/byrating"  },
        { title: qsTr("Abyss"),         url: "http://bash.im/abyss"     },
        { title: qsTr("Abyss top"),     url: "http://bash.im/abysstop"  },
        { title: qsTr("Abyss best"),    url: "http://bash.im/abyssbest" },
    ],
    eng: [
        { title: "Latest",              url: "http://bash.org/?latest" },
        { title: "Browse",              url: "http://bash.org/?browse" },
        { title: "Random",              url: "http://bash.org/?random" },
        { title: "Top",                 url: "http://bash.org/?top"    }
    ]
}

QML中的代码在行“eng：[”给出错误，错误“预期lexem”，但在纯javascript中一切正常。怎么了？

试试这个

property var pagesAllModels: {
    ru: [
        { title: qsTr("New"),           url: "http://bash.im"           },
        { title: qsTr("Random"),        url: "http://bash.im/random"    },
        { title: qsTr("Best"),          url: "http://bash.im/best"      },
        { title: qsTr("By rating"),     url: "http://bash.im/byrating"  },
        { title: qsTr("Abyss"),         url: "http://bash.im/abyss"     },
        { title: qsTr("Abyss top"),     url: "http://bash.im/abysstop"  },
        { title: qsTr("Abyss best"),    url: "http://bash.im/abyssbest" }
    ],
    eng: [
        { title: "Latest",              url: "http://bash.org/?latest" },
        { title: "Browse",              url: "http://bash.org/?browse" },
        { title: "Random",              url: "http://bash.org/?random" },
        { title: "Top",                 url: "http://bash.org/?top"    }
    ]
}

希望这能解决您的问题

关联数组以分号＆＃34; ; ＆＃34;

分隔

试试这个

property var pagesAllModels: {
    ru: [
        { title: qsTr("New"),           url: "http://bash.im"           },
        { title: qsTr("Random"),        url: "http://bash.im/random"    },
        { title: qsTr("Best"),          url: "http://bash.im/best"      },
        { title: qsTr("By rating"),     url: "http://bash.im/byrating"  },
        { title: qsTr("Abyss"),         url: "http://bash.im/abyss"     },
        { title: qsTr("Abyss top"),     url: "http://bash.im/abysstop"  },
        { title: qsTr("Abyss best"),    url: "http://bash.im/abyssbest" },
    ];
    eng: [
        { title: "Latest",              url: "http://bash.org/?latest" },
        { title: "Browse",              url: "http://bash.org/?browse" },
        { title: "Random",              url: "http://bash.org/?random" },
        { title: "Top",                 url: "http://bash.org/?top"    }
    ]
}

那是因为你的代码是非法的JSON数组定义。 Web浏览器正在接受它，因为它们对JS语法并不严格，但QML引擎非常严格：

在关联数组中的键：值对中，键必须是字符串，因此它必须有引号，否则会与（不存在的）变量名混淆。

property var pagesAllModels: {
    "ru": [
        { "title": qsTr("New"),           "url": "http://bash.im"           },
        { "title": qsTr("Random"),        "url": "http://bash.im/random"    },
        { "title": qsTr("Best"),          "url": "http://bash.im/best"      },
        { "title": qsTr("By rating"),     "url": "http://bash.im/byrating"  },
        { "title": qsTr("Abyss"),         "url": "http://bash.im/abyss"     },
        { "title": qsTr("Abyss top"),     "url": "http://bash.im/abysstop"  },
        { "title": qsTr("Abyss best"),    "url": "http://bash.im/abyssbest" }
    ],
    "eng": [
        { "title": "Latest",              "url": "http://bash.org/?latest" },
        { "title": "Browse",              "url": "http://bash.org/?browse" },
        { "title": "Random",              "url": "http://bash.org/?random" },
        { "title": "Top",                 "url": "http://bash.org/?top"    }
    ]
}

它有效！
