A number holds a numerical value. Although if you want to use this way of doing it then I'm of no help as I haven't used freemarker before unfortunately. 0 该问题是怎么引起的？(最新版上已修复的会直接close掉) 重现步骤 However, when in doubt you can use always use expr!?size > 0 or expr!?length > 0 instead of expr?has_content. Do: var isTrueSet = (myValue === 'true'); Use the strict equality operator (===), which doesn't make any implicit type conversions when the compared variables have different types.
