如何使用JavaScript从文本中删除基于冒号的表情符号

Question

How can i remove all instances of :smile: style emjois from a string using javascript? Here is an example below I got in JSON with :point_right: in it. I'd love to remove all of them from a string.

[ { service_name: 'Instagram',
   title: 'Instagram: “:point_right: Real people, making real products from real plants, using their actual hands to put them in boxes that show up on your doorstep.…”',
   text: '36 Likes, 2 Comments - “:point_right: Real people, making real products',
  ts: '1523497358.000299' }

Answer 1

Just use String.prototype.replace() with a regular expression:

 const input = 'Instagram: “:point_right: Real people, making real products from real plants, using their actual hands to put them in boxes that show up on your doorstep.…”'; const output = input.replace(/:\\w+:/g, ''); console.log(output); 

Answer 2

Assuming the emojis are all one word, between : s:

 const obj = { service_name: 'Instagram', title: 'Instagram: “:point_right: Real people, making real products from real plants, using their actual hands to put them in boxes that show up on your doorstep.…”', text: '36 Likes, 2 Comments - “:point_right: Real people, making real products', ts: '1523497358.000299' } obj.title = obj.title.replace(/:[^ ]+:/g, ''); obj.text = obj.text.replace(/:[^ ]+:/g, ''); console.log(obj); 

Answer 3

From this answer Replacing values in JSON object you could do this :

 var json=[ { service_name: 'Instagram', title: 'Instagram: “:point_right: Real people, making real products from real plants, using their actual hands to put them in boxes that show up on your doorstep.…”', text: '36 Likes, 2 Comments - “:point_right: Real people, making real products', ts: '1523497358.000299' }]; var rep = JSON.stringify(json).replace(/(“)(:[^:]+:)/g, '$1'); var New = JSON.parse(rep); console.log(New); 

Answer 4

Try this :

 // JSON Object var jsonObj = [{ "service_name": "Instagram", "title": "Instagram: “:point_right: Real people, making real products from real plants, using their actual hands to put them in boxes that show up on your doorstep.…”", "text": "36 Likes, 2 Comments - “:point_right: Real people, making real products", "ts": "1523497358.000299" }]; // Replace :point_right: with blank string. jsonObj.map(obj => { obj.title = obj.title.replace(":point_right: ", ""); obj.text = obj.text.replace(":point_right: ", ""); return obj; }); // Output console.log(jsonObj);
