I am currently facing an issue with a string that contains multiple words. I need to replace a specific phrase, but there are several similar phrases that also need replacement.
Below are the strings that require replacement (or removal):
- "fox jumps over the lazy dog"
- "fox jumps over the lazy cat"
- "fox jumpa over the lazy cat"
- "fox jumpaoverthe lazy cat" (note: some spaces might be missing between words)
The replacement should be case insensitive and global
Example 1: var str = "The quick brown fox jumpa over the lazy dog"; // the result would be "The quick brown "
Example 2: str = "The quick brown fox jump over the lazy dog"; // the result would be "The quick brown "
Example 3: str = "The quick brown fox jump over the lazy cat"; // the result would be "The quick brown "
Example 4: str = "The quick brown fox jumpa over the lazy cat"; // the result would be "The quick brown "
Example 5: str = "The quickbrownfoxjumpaoverthe lazy cat"; // the result would be "The quick brown "
I have tried the following code without success:
let str1 = "The quick brown fox jumpa overthe lazy cat";
let reg = /The\s*quick\s*brown\s*fox\s*jump[s|a]\s*over\s*the\s*lazy [\bcat\b|\bdog\b]/gi;
let res = str1.replace(reg, "");
console.log(res); //should be empty
str1 = "The quickbrownfox jumps overthe lazy cat";
res = str1.replace(reg, "");
console.log(res); //should be empty
