Compare to qml string "10" and "9"
I've tried to compare qml string "10" biggest than "9", but console.log sent me false
console.log("10" > "9");
console output false
Explain to me why this doesn't work

I will quote the relevant part and present my own example:
The algorithm to compare two strings is simple:
- Compare the first character of both strings.
- If the first character from the first string is greater (or less) than the other string’s, then the first string is greater (or less) than the second. We’re done.
- Otherwise, if both strings’ first characters are the same, compare the second characters the same way.
- Repeat until the end of either string.
- If both strings end at the same length, then they are equal. Otherwise, the longer string is greater.
console.log("10" > "9"); // false, first character is smaller console.log("9" > "8"); // true, first character is larger console.log("9" > "08"); // true, first char. is larger console.log("10" > "09"); // true, first char. is larger console.log("100" > "11"); // false, second char. is smaller
If you know the strings will be integers always (assuming they will come from some variable) you can change your code to parse them and the comparison will work correctly:
console.log(parseInt("10") > parseInt("9"));
QML If statement matching strings in a variable ?, I am searching a way to match words within a string message I received from websockets which is stored in a variable using an IF statement. so� Compares this string with the other string and returns an integer less than, equal to, or greater than zero if this string is less than, equal to, or greater than the other string. The comparison is performed in a locale- and also platform-dependent manner. Use this function to present sorted lists of strings to the user.
You can use this workaround:
console.log("10"*1 > "9"*1); // true
If you are going to use parseInt take care about the radix parameter. In previus example there is no radix parameter, so the interpreter will fall back to the default behaviour, which typically treats numbers as decimal, unless they start with a zero (octal) or 0x (hexadecimal)
What the Heck is the Strict Comparison Operator, Hi Brad I'm new to Qt Quick and while I've been learning the QML That is if you try to compare a string to an Number that is exactly what will� C# String.Compare method compares two strings in C#. You can also use C# String.Equals method and StringComparer class and its method. This article and code examples demonstrate how to compare strings in C# using these different methods.
[Qt-qml] qml locale aware string comparison, Hi guys,. Are there are any plans to implement locale aware string comparison api for QML? What about any other locale aware properties, including but not� The algorithm to compare two strings is simple: Compare the first character of both strings. If the first character from the first string is greater (or less) than the other string’s, then the first string is greater (or less) than the Otherwise, if both strings’ first characters are the same,
TestCase QML Type, This function dynamically creates a QML object from the given qml string with the specified compare(findChild(item, "childObject"), expectedChildObject);. The comparison operators which use three characters vs. two are called the Strict Comparison Operator and is not new to QML but rather part of the ECMAScript standard. For those unfamiliar ECMAScript is the actual scripting language standardized in ECMA-262 and ISO/IEC 16262 .
[Qt-qml] qml locale aware string comparison, [Qt-qml] qml locale aware string comparison. Alan Alpert alan.alpert at nokia.com. Fri Dec 23 02:18:04 CET 2011. Previous message: [Qt-qml] qml locale aware� In qml the qsTr() does take arguments in the same way as QString does. You can write qsTr("%1 copied").arg(filename). This will translate the string and then format it using the argument. At least it works fine with string arguments.
