You could use document.querySelectorAll() that allows you to specify multiple ids in a CSS selector string . … Read more
This is an old posting but maybe still useful for someone. I had the same error message. In the end the problem was an invalid name for the second argument, i.e., I had a line like: window.open(‘/somefile.html’, ‘a window title’, ‘width=300′); The problem was ‘a window title’ as it is not valid. It worked fine … Read more

You can also use Js2Py which is written in pure python and is able to both execute and translate javascript to python. Supports virtually whole JavaScript even labels, getters, setters and other rarely used features. import js2py js = “”” function escramble_758(){ var a,b,c a=”+1 ” b=’84-‘ a+=’425-‘ b+=’7450’ c=”9″ document.write(a+c+b) } escramble_758() “””.replace(“document.write”, “return … Read more
You are more vulnerable to attacks if using eval: JSON is a subset of Javascript and json.parse just parses JSON whereas eval would leave the door open to all JS expressions.
The reduce is good for stuff like this: to perform aggregate operations (like min, max, avg, etc.) on an array of objects, and return a single result: myArray.reduce(function(prev, curr) { return prev.Cost < curr.Cost ? prev : curr; }); …or you can define that inner function with ES6 function syntax: (prev, curr) => prev.Cost < … Read more

I just wrote this function that does what you want; try it out let me know if it doesn’t work correctly for you: // Test with an element. var initElement = document.getElementsByTagName(“html”)[0]; var json = mapDOM(initElement, true); console.log(json); // Test with a string. initElement = “<div><span>text</span>Text2</div>”; json = mapDOM(initElement, true); console.log(json); function mapDOM(element, json) { … Read more
React Router Hash Link worked for me and is easy to install and implement: $ npm install –save react-router-hash-link In your component.js import it as Link: import { HashLink as Link } from ‘react-router-hash-link’; And instead of using an anchor <a>, use <Link> : <Link to=”home-page#section-three”>Section three</Link> Note: I used HashRouter instead of Router:
In version 0.2.13, You should be able to pass objects into $state.go, $state.go(‘myState’, {myParam: {some: ‘thing’}}) $stateProvider.state(‘myState’, { url: ‘/myState/{myParam:json}’, params: {myParam: null}, … and then access the parameter in your controller. $stateParams.myParam //should be {some: ‘thing’} myParam will not show up in the URL.
