'TypeError: name.push is not a function' 同时将字符串推入空数组

Question

I have a multi line string which I am trying to extract some information by splitting the string and push to some empty arrays. But I am having some type error while trying to push array. My code as below. I did some research in stack overflow and some suggestion is to put the array [] as dictionary {} . But I don't want any dictionary. Can someone help?

 < script > var str = `PP 0800 / 00 / XX: Units: 2: Total: 4.70 || PP 0800 / 00 / XX: Units: 1: Total: 2.35 ||` //This is the multi line string var singleLine = str.replace(/(\r\n|\n|\r)/gm, ""); //Converting multi line string into a single line var splittedArray = singleLine.split("||"); //splitting the string based on the symbol || var name = []; //Initializing three empty arrays var unit = []; var total = []; for (i = 0; i < splittedArray.length - 1; i++) { //Looping through the splittedArray var furtherSplit = splittedArray[i].split(":"); //Splitting each array further based on the symbol: name.push(furtherSplit[0]); //This is where name, unit and total pushing into three separate arrays unit.push(furtherSplit[2]); total.push(furtherSplit[4]); // alert(furtherSplit[0]); //This is showing the name correctly } </script>

Don't use var name since it's reserved for the window scope and Quirks to "" String.
In contrast, by using const , let , (instead of var ) your variables are now instantiated and inside its own block scope (not window ).
Also, when you do a for loop with < use just length , not length - 1

 const str = `PP 0800 / 00 / XX: Units: 2: Total: 4.70 || PP 0800 / 00 / XX: Units: 1: Total: 2.35 ||`; const lines = str.split(/\n/); const name = []; const unit = []; const total = []; for (let i = 0; i < lines.length; i++) { const parts = lines[i].replace("||", "").split(":"); name.push(parts[0].trim()); unit.push(parts[2].trim()); total.push(parts[4].trim()); } console.log(name, unit, total)
