如何从与其他值聚合的jquery中的数组中删除\\ n

Question

i have a array something like this ["\\n robort \\n \\ electronic","automated machine\\narm"];

how can i remove \\n from this array. so that my result will look like

[" robort electronic","automated machine arm"]

i'm able to remove seperate(or segregated) \\n with this code

 var arr = ["\\n", "\\n roborts\\n"]; var removeItem = '\\n'; arr = jQuery.grep(arr, function(value) { return value != removeItem; }); console.log(arr); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script> 

Answer 1

You can map it back, and remove the newlines from each index, and filter out any that are just newlines

 var arr = ["\\n robort \\n \\ electronic","automated machine\\narm", "\\n"]; arr = arr.filter(function(item) { return item !== "\\n"; }).map(function(item) { return item.replace(/\\n/g,''); }); console.log(arr) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 

Answer 2

Without jQuery:

 var arr = ["\\n", "\\n roborts\\n"].map(function(val) { return val.replace(/\\n/g, ""); }); console.log(arr); 

This uses Array.prototype.map() to return an array consisting of the parts of your existing array but with the newline character removed.

User map() ( Link ) array and replace() function.

Code

var arr = ["\nautomated machine\narm", "\n roborts \n"];
var removeItem = /\n/g;

arr = arr.map( function(value) {
  return value.replace(removeItem, "");
});

console.log(arr);
