在TypeScript中使用JsObservable需要帮助吗?

标签: javascript typescript jsrender jsviews

我过去曾经使用过JSRender,JSViews和JSObservables。这一次,我开始了一个新项目但是使用TypeScript并且我不确定如何使用它...我发现将引用放在.js,.d.ts,.ts等的地方非常混乱......

我可以请描述一下我所拥有的,失败的地方,以及你是否可以提供一些指导....这会给我一个很好的开始!

我的“scripts”文件夹包含以下文件:

~\Typings\jQuery\jQuery.d.ts
installed from this NuGet package: jquery.TypeScript.DefinitelyTyped v0.0.1

~\Typings\jsrender\jsrender.d.ts   
installed from this NuGet package: jsrender.TypeScript.DefinitelyTyped v0.1.8

文件:〜/ index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <script src="scripts/jquery-3.1.1.js"></script>
    <script src="scripts/jsviews.js"></script>

        <div id="myMap"></div>
        <div id="optionsTmpl"></div>
    </div>
</body>
</html>

文件:〜/ tmpl / options.tmpl.html

<div class="optionsFrame">
    <select data-link="mapType">
    {^{for mapTypes}}
        <option value="{{:id}}">{{:name}}</option>
    {{/for}}

        this.game.loadMap();
    }
}

    var app = new UnchartedApp();
    app.init();
};

    /*****      Error on the $.observe() line !!    *****/
    loadMap() {
        this.linkTemplate("options", "#optionsTmpl", this).done(function (currentGame) {
            $.observe(currentGame, "*", currentGame.modelChangeHandler);
        });
    }

    modelChangeHandler(ev, eventArgs) {
        if (ev.type == "propertyChange") {
            var _game: UnchartedGame = ev.currentTarget;

                try {
                    _game.myMap.setMapType(mapTypeNames[newValue]);
                }
                catch (ex) {
                }
            }
        }
    }

    loadTemplate(tmplName: string) {
        var deferredLoad = $.Deferred();
        try {
            var filePath: string = "../tmpl/" + tmplName + ".tmpl.html";
            $.get(filePath).then(function (templateText) {
                $.templates(tmplName, templateText);
                deferredLoad.resolve();
            })
        }
        catch (e) {
            deferredLoad.reject();
        }
        return deferredLoad.promise();
    }

    linkTemplate(tmplName: string, targetId: string, model: UnchartedGame) {
        var deferredLink = $.Deferred();
        try {
            this.loadTemplate(tmplName).done(
            function () {
                $.templates[tmplName].link(targetId, model);
                deferredLink.resolve(model);
            });
        }
        catch (e) {
            deferredLink.reject();
        }
        return deferredLink.promise();

谢谢和问候,

TypeScript希望您使用ES6导入语句,即:import * as jQuery from 'jquery';另一种方法是在模块加载器中引用脚本(例如jquery),然后使用declare const jQuery: any来使用整个申请过程中。另一种方法是在tsconfig中引用输入:

使用import语句的第一种方式:

import * as jQuery from 'jquery'; // jquery installed via npm install jquery
import * as jsrender from 'jsrender'; // jsrender installed via npm install jsrender

// === OR ===

declare const jQuery: any; // Reference the script in your module loader/html
declare const jsrender: any; // Reference the script in your module loader/html

class UnchartedGame {
    constructor() {
    }


/*****      Error on the $.observe() line !!    *****/
loadMap() {
    this.linkTemplate("options", "#optionsTmpl", this).done(function (currentGame) {
        $.observe(currentGame, "*", currentGame.modelChangeHandler);
    });
}

modelChangeHandler(ev, eventArgs) {
    if (ev.type == "propertyChange") {
        var _game: UnchartedGame = ev.currentTarget;
        if (eventArgs.path == "mapType") {
            try {
                _game.myMap.setMapType(mapTypeNames[newValue]);
            }
            catch (ex) {
            }
        }
    }
}

loadTemplate(tmplName: string) {
    var deferredLoad = $.Deferred();
    try {
        var filePath: string = "../tmpl/" + tmplName + ".tmpl.html";
        $.get(filePath).then(function (templateText) {
            $.templates(tmplName, templateText);
            deferredLoad.resolve();
        })
    }
    catch (e) {
        deferredLoad.reject();
    }
    return deferredLoad.promise();
}

linkTemplate(tmplName: string, targetId: string, model: UnchartedGame) {
    var deferredLink = $.Deferred();
    try {
        this.loadTemplate(tmplName).done(
        function () {
            $.templates[tmplName].link(targetId, model);
            deferredLink.resolve(model);
        });
    }
    catch (e) {
        deferredLink.reject();
    }
    return deferredLink.promise();
}

}

使用TSConfig:

{
  "compilerOptions": {
    "types": ["jquery", "jsrender"]
  }
}

另一种可能的方法是转到主模块并使用以下行:

import 'jquery'; // jquery installed via npm install jquery

我注意到我在我的一个项目中使用它(需要@types文件)。

我还建议不要使用引用路径,因为TypeScript是关于类型的。大多数模块(从我到目前为止看到的)附带一个打字文件。但是,例如jQuery没有。因此,在执行npm install jquery之后,您还需要运行npm install @types/jquery --save-dev

来另外安装它的类型
