如何使用JavaScript将arraylist中的逗号'，'替换为'/'

Question

How can I replace ',' with a '/' in an array list using javascript. Here my array-list has two string 'values separated by a comma ',' but I want to make it in form of a single string separating the values by '/' ?

For eg : array[] = { value1, a1/a2/a3} to be replaced by array[] = {value1/a1/a2/a3}

For example: Here I want to replace the outcome which comes as [3,101/102/103] by [3/101/102/103].

Can anyone please suggest ?

Answer 1

这将使用完整的字符串组成一个元素数组：

var newArr = arr.join(',').replace(/,/g, '/').split();

Answer 2

Another option is

var array = ['1', '2/3/4/5'], array2 = [];

array2.push(array.join('/'));

Answer 3

String.prototype.replaceAll = function(target, replacement) {
  return this.split(target).join(replacement);
};
array = new Array("a1/a2/a3")

for (i = 0; i < array.length; ++i) {
    array[i] = array[i].replaceAll("/",",")
}

does this help?
