I'm bundling JS and CSS (compiled from SCSS) into two separate bundles, one for 3rd party (vendor) and one for the project code (company). I'm able to access jQuery via $ successfully from scripts in the company bundle as a global, such as from some-other-script.js, without any issues. However when trying to call the stickyTableHeaders function from the StickyTableHeaders plugin in table-headers.js: Uncaught TypeError: $(...).stickyTableHeaders is not a function. I don't get any other errors about loading scripts etc. and I can see that vendor.bundle.js includes the plugin code.
Additionally I see from the bottom of the plugin source that the function is meant to be added to $ as follows:
$.fn[name] = function ( options ) {
return this.each(function () {
var instance = $.data(this, 'plugin_' + name);
if (instance) {
if (typeof options === 'string') {
instance[options].apply(instance);
} else {
instance.updateOptions(options);
}
} else if(options !== 'destroy') {
$.data(this, 'plugin_' + name, new Plugin( this, options ));
}
});
};
- Any ideas why it can't find the function on the $ (jQuery) object?
- This question seems similar, however the poster was having trouble with the plugin not being able to find jQuery in that case. Additionally I'm not sure if using the import-loader as per one of the suggestions is the right approach in my case, or if I'm doing something fundamentally wrong. You can see commented out lines in the webpack.config.js below where I've tried to register sticky-table-headers as a plugin with webpack without success - same result.
My webpack.config.js is as follows:
var path = require('path');
var webpack = require('webpack');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var extractSass = new ExtractTextPlugin({
filename: "[name].bundle.css",
disable: process.env.NODE_ENV === "development"
});
module.exports = function (env) {
env = env || {};
var isProd = env.NODE_ENV === 'production';
// Setup base config for all environments
var config = {
entry: {
vendor: './Client/js/vendor',
company: './Client/js/company' // Includes all SCSS, which ends up in company.bundle.css via extract-text-webpack-plugin.
},
output: {
// ReSharper disable once UseOfImplicitGlobalInFunctionScope
path: path.join(__dirname, 'wwwroot/dist'),
filename: '[name].bundle.js'
},
devtool: 'eval-source-map',
mode: "development",
resolve: {
extensions: ['.ts', '.tsx', '.js', '.jsx'],
alias: {
"jquery.validation": "jquery-validation/dist/jquery.validate.js",
//"sticky-table-headers": "sticky-table-headers/js/jquery.stickytableheaders.js"
}
},
plugins: [
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
'window.jQuery': 'jquery',
Popper: ['popper.js', 'default'],
//"sticky-table-headers": ["sticky-table-headers", "default"]
}),
extractSass
],
module: {
rules: [
{
test: /\.scss$/,
use: extractSass.extract({
use: [{
loader: "css-loader"
}, {
loader: "sass-loader"
}],
// use style-loader in development
fallback: "style-loader"
})
}
]
}
}
// Alter config for prod environment
if (isProd) {
config.devtool = 'source-map'; // SourceMap emitted as a separate file.
//Normally disallow access on webserver or use (none) instead. Internal
//app so leaving them accessible for easier support.
config.mode = "production";
}
return config;
};
Then in vendor.js I have:
import 'jquery';
import 'popper.js';
import 'bootstrap';
import "jquery-validation";
import "jquery-validation-unobtrusive";
import "sticky-table-headers";
In company.js I have:
import '../scss/site.scss';
import './site';
import './some-other-script';
import './table-headers';
Finally in table-headers.js I have:
(function () {
$(function () {
if ($(".my-sticky-table-header").length === 0) return;
var offset = $('.navbar').height();
$(".my-sticky-table-header").stickyTableHeaders({
fixedOffset:offset});
});
})();
Thanks.
