I may be overlooking something very obvious, but here is my dilemma. I am trying to convert [ 'hr' ] into [ '* * *' ]. This is what I tried:
var hr = jsonml[i]
console.log(hr)
// outputs: [ 'hr' ]
hr.replace(/hr/g, '* * *')
However, I am encountering this error:
TypeError: Object hr has no method 'replace'
Can someone point out what I am missing here?
Since the variable hr is of type Array, you can attempt the following:
hr[0] = hr[0].replace(/hr/g, '* * *');
Alternatively, you can try:
hr = hr[0].replace(/hr/g, '* * *');
The variable called hr is actually an array that holds a single string element. Here is how I would handle it:
if (hr.length > 0)
hr[0] = hr[0].replace(/hr/g, '* * *');
Alternatively, you could use a loop to handle multiple elements:
for (var i = 0; i < hr.length; i++)
hr[i] = hr[i].replace(/hr/g, '* * *');
This is useful in case the hr array contains more than one element.
Check the type of the specific object :
alert(typeof hr);
Upon running this code snippet, you'll realize that the object is actually an array!
Now, implement the following code:
for (let j = 0; j < hr.length; j++) {
let output = hr[j].replace(/hr/g, '* * *');
}
Here is a concise solution that fulfills the exact requirements posed by the original poster:
hr = [hr[0].replace('hr', '* * *')];
There is no necessity for utilizing a regular expression for the replacement in this context.
