我在index.html中创建了模板，以使用js生成html代码，以下代码。我的Webpack配置也在下面。当我使用webpack-dev-server运行它时，出现错误:未定义标题。 Webpack以某种方式尝试自行解析“标题”，而不是将其委托(delegate)给“lodash / template”。请帮助我修复代码，我很沮丧(。

问题是html-webpack-plugin使用相同的模板标签<%= %>将 bundle 包信息插入模板。
您有两个选择。
1.更改lodash.template分隔符
您可以将客户端lodash /模板使用的分隔符更改为其他分隔符，因此Webpack会忽略它。例如:
_.templateSettings.interpolate = /<\$=([\s\S]+?)\$>/g;
_.templateSettings.interpolate = /<\$=([\s\S]+?)\$>/g;
const temp = _.template
const titlePicDiscHalf = temp(document.getElementById('titlePicDiscHalf').innerHTML);
document.write(titlePicDiscHalf({ title: 'Hello World!' }));<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js"></script>
<script type="text/template" id="titlePicDiscHalf">
<div class="titlePicDiscHalf">
<div class="picture"></div>
<div class="title">
<$=title$>
</div>
<div class="discription"></div>
<div class="buttons"></div>
</div>
</script>2.更改html-webpack-plugin分隔符
分别安装
ejs-loader并配置html-webpack-plugin以使用它来加载模板。您可以在那里更改定界符。它可能看起来像这样:plugins: [
new HtmlWebpackPlugin({
template: './index.html.ejs',
})
],
module: {
rules: [
{ test: /\.ejs$/, loader: 'ejs-loader', query: {
interpolate: /<\$=([\s\S]+?)\$>/g,
evaluate: /<\$([\s\S]+?)\$>/g,
}},
]
},
html-webpack-plugin:<!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<title><$= htmlWebpackPlugin.options.title $></title>
</head>
<body>
<script type="text/template" id="titlePicDiscHalf">
<div class="titlePicDiscHalf">
<div class="picture"></div>
<div class="title"><%= title %></div>
<div class="discription"></div>
<div class="buttons"></div>
</div>
</script>
</body>
</html>
<title><$= htmlWebpackPlugin.options.title $></title>，客户端lodash使用<div class="title"><%= title %></div>。
