问题描述
我正在检查JAVASCRIPT中字符串的索引.这是错误的.该值属于哪个位置，如下所示:
I am checking an index Of string in JAVASCRIPT. and this is coming as false. where as the value does belong to it as below :
if(idOfControl.indexOf(idOfButton)) == is giving false for the below values.
idOfControl = "dlInventory_btnEditComment_0"
idOfButton = "dlInventory_btnEditComment"
但是如果我运行idOfControl.replace(idOfButton, "");，它可以正常工作并替换文本.
But if I run idOfControl.replace(idOfButton, ""); It is working and replacing the text.
任何原因吗?
推荐答案
indexOf也可以返回0. 0评估为false.试试:
indexOf can also return 0, in the event of your string being found at the position 0. 0 evaluates to false. Try:
if(idOfControl.indexOf(idOfButton) > -1)
