But there are disadvantages, such as requiring the input to be properly formatted JSON.īy using string.replace similar to how I used string.split above, you can fix the input. It has some other advantages such as support for nested lists. It may feel like a bit of a hack, but it's simple and highly optimized by most Javascript engines. Tip: If an empty string ('') is used as the separator, the string is split between each character. map(x => (x = '') ? '' : (isNaN(Number(x)) ? x : Number(x)) ) Definition and Usage The split() method is used to split a string into an array of substrings, and returns the new array. ) // numbers, empty values default to zeroĬonsole.log( num.split(/+/).map(Number) ) // spaces trimmed, empty values NOT skipped toString (): If you are looking for the simplest way it's better to use toString () like this: var arr 'Zero', 'One', 'Two' console.log (arr. ) // spaces trimmed, empty values skipped To convert an array to a string with a comma in javascript, we use the join method to bring the array to the variable sub. Try it Syntax js JSON.stringify(value) JSON.stringify(value, replacer) JSON. ) // spaces NOT trimmed, empty values included The JSON.stringify () static method converts a JavaScript value to a JSON string, optionally replacing values if a replacer function is specified or optionally including only the specified properties if a replacer array is specified. I quickly fiddled this together: (function($) ', restString) īlock = $.trim(block) + getBlock(']', restString) So how would you interpret that? And what do you want the result to be? An array with: orĮven if you escape the comma, you'd have a problem. join('') with the empty string '' as the separator character not. In the resulting array, each element is a string containing one character, so we reverse the process by calling. Observe the following: var myArr = "a,b,c,d,e,f,g,','" In the code examples, we turn a string with commas into an array without commas by calling. Hmm, split is dangerous IMHO as a string can always contain a comma. Example 1:
