How do I delete words that start with the keyword in the object value? javascript-CodePudding

I have an array like this. I want to delete row-? words in classname.

[
  {
    type: "text",
    name: "text-1632646960432-0",
    satir: "1",
    className: "form-control col-lg-3 row-1"
  },
  {
    type: "text",
    name: "text-1632646974512-0",
    satir: "1",
    className: "form-control col-lg-6 row-8"
  }
]

I want a result like this.

[
  {
    type: "text",
    name: "text-1632646960432-0",
    satir: "1",
    className: "form-control col-lg-3"
  },
  {
    type: "text",
    name: "text-1632646974512-0",
    satir: "1",
    className: "form-control col-lg-6"
  }
]

How can I do that ? Also how can I trim so that there is no space at the end?

1) You can

const arr = [{
    type: "text",
    name: "text-1632646960432-0",
    satir: "1",
    className: "form-control col-lg-3 row-1",
  },
  {
    type: "text",
    name: "text-1632646974512-0",
    satir: "1",
    className: "row-12 form-control row-6 col-lg-6 row-8",
  },
];

const result = arr.map((o) => ({
  ...o,
  className: o.className.replace(/\s*row-\d /g, "").trim(),
}));

console.log(result);

/* This is not a part of answer. It is just to give the output fill height. So IGNORE IT */
.as-console-wrapper { max-height: 100% !important; top: 0; }

or /\s*row-[^\s] \s*/g

const result = arr.map((o) => ({
  ...o,
  className: o.className.replace(/\s*row-[^\s] \s*/g, " ").trim(),
}));

You can use .replace(/row-\d /g, '').replace(/\s /g, ' ').trim() to remove it.

You can check the live demo here:

const input = [{
    type: "text",
    name: "text-1632646960432-0",
    satir: "1",
    className: "form-control col-lg-6 row-8"
  },
  {
    type: "text",
    name: "text-1632646974512-0",
    satir: "1",
    className: "form-control col-lg-6 row-8"
  },
  {
    type: "text",
    name: "text-1632646974512-0",
    satir: "1",
    className: "form-control row-12 col-lg-6 row-8"
  }
];

input.forEach((item) => {
  item.className = item.className.replace(/row-\d /g, '').replace(/\s /g, ' ').trim();
});

console.log(input);
