The js replace method solves the whole replacement problem (multiple replacement target strings can be used)

2. Use the replace function, where the first Chinese text is replaced with an empty string, but there are two Chinese text that are not replaced:

3. Add a while loop to determine if the word “China” still exists using the “indexOf” function. If so, continue to replace, end not to replace, then all target strings have been replaced:
