问题描述

我使用的是Win 10(64位)，并且已经在Eclipse Photon和版本2018-09(两次都是64位版本)中进行了尝试，但是两种方式我都得到了相同的结果:

I'm using Win 10 (64bit) and I've tried this with Eclipse Photon and version 2018-09 (64 bit version both times) but I'm getting the same result with both:

我创建了一个新项目(文件>新建>项目...:JavaScript> JavaScript项目)和一个JavaScript脚本(文件>新建> JavaScript源文件).如果输入

I created a new project (File > New > Project...: JavaScript > JavaScript Project) and a JavaScript script (File > New > JavaScript Source File). If I type

function test() {
    var inputField = doc
}

然后按 + ，它应该给我一个建议列表，但列表只显示无默认建议" .如果在写完文档后再次按 + .列表仅显示"MISSING" .

then press +, it should give me a list of suggestions but instead the list only says "No Default Proposals".If I press + again after writing document. the list only says "MISSING".

在HTML文件的< script></script> 部分内编写代码将导致相同的空白窗口.对于HTML和CSS的建议通常可以奏效，但有时窗口甚至根本无法打开，如果我写的是< sty ，没有关于< style> 的建议.

Writing code inside the <script></script> part of an HTML file results in the same empty window.Suggestions for HTML and CSS often work but sometimes the window doesn't even open in the first place and if I write e.g. <sty, there's no suggestion for <style>.

如果我编写例如，我可以用某种方式训练Eclipse:

I can train Eclipse in a way if I write e.g.:

var inputField = document.getElementById("inputField");
inputField.style = "red";

再次编写 inputField 后，按 + 会提示样式" .这仅在同一个文件中有效，如果我在不同的脚本中获得了相同的输入字段，则不建议使用"style" .

Pressing + after writing inputField again suggests "style". This only works within the same file, if I get the same input field in a different script, there's no suggestion for "style".

我没有更改任何设置( Window> Prerferences ):

I haven't changed anything about the settings (Window > Prerferences):

JavaScript>编辑器>内容辅助:未选中启用自动激活"(我不希望这样做)，并且启用它不会更改任何内容
JavaScript-编辑器-内容辅助-高级:单击(我尝试检查除"Word Proposals"之外的所有内容，但没有任何变化)
Web> HTML文件>编辑器>内容辅助:所有内容均已检查
Web> CSS文件>编辑器>内容辅助:所有内容均已检查

JavaScript > Editor > Content Assist: "Enable auto activation" isn't checked (I don't want it to do that) and enabling it doesn't change anything
JavaScript - Editor - Content Assist - Advanced: click (I tried checking everything except "Word Proposals" but no change)
Web > HTML Files > Editor > Content Assist: Everything is checked
Web > CSS Files > Editor > Content Assist: Everything is checked

我正在将Mars.2用于Java项目，并且在那里一切正常，所以不确定是否是该版本(我不想为新的JS项目使用旧的版本)，或者Eclipse是否可以无法正确处理JS.

I'm using Mars.2 for a Java project and everything works fine there, so not sure if it's the version (I don't want to use a version that old for the new JS project) or if Eclipse simply can't handle JS properly.

任何想法/建议我可以尝试解决此问题(无需安装额外的插件)吗?

Any ideas/suggestions what I could try to fix this (without installing extra plugins)?

我刚刚尝试了两个以上的版本:它可与Mars.2(PHP)一起使用，但不适用于Neon.我仍然更喜欢修复Photon或2018-09，而不是使用将近3年前发布的版本.

I just tried 2 more versions: It works with Mars.2 (PHP) but not with Neon. I'd still prefer fixing Photon or 2018-09 though instead of using a version that was released almost 3 years ago.
