Javascript正则表达式从字符串中删除字符和数字

Question

我有这个字符串，我需要从包含它们的所有单词中删除下划线编号。

"View":{"Name":"Untitled-4","Image_1":{"BackgroundImage":"Image.png","Position":[0,0],"Width":320,"Height":480},"Button_1":{"BackgroundImage":"ButtonTop.png","Position":[61,83],"Width":217,"Height":58},"Button_2":{"BackgroundImage":"ButtonBottom.png","Position":[81,114],"Width":205,"Height":73},"TextField_1":{"BackgroundImage":"TextFieldLogin.png","Position":[102,336],"Width":189,"Height":31},"Label_1":{"Position":[137,100],"Width":54,"Height":20,"Text":"HiRob","FontSize":18,"Color":[0,0,0,1]},"Label_2":{"Position":[43,342],"Width":72,"Height":20,"Text":"LogOut:","FontSize":18,"Color":[0,0,0,1]},"Label_3":{"Position":[115,234],"Width":126,"Height":20,"Text":"AnotherButton","FontSize":18,"Color":[0,0,0,1]}}

我正在寻找的输出是：

"View":{"Name":"Untitled-4","Image":{"BackgroundImage":"Image.png","Position":[0,0],"Width":320,"Height":480},"Button":{"BackgroundImage":"ButtonTop.png","Position":[61,83],"Width":217,"Height":58},"Button":{"BackgroundImage":"ButtonBottom.png","Position":[81,114],"Width":205,"Height":73},"TextField":{"BackgroundImage":"TextFieldLogin.png","Position":[102,336],"Width":189,"Height":31},"Label":{"Position":[137,100],"Width":54,"Height":20,"Text":"HiRob","FontSize":18,"Color":[0,0,0,1]},"Label":{"Position":[43,342],"Width":72,"Height":20,"Text":"LogOut:","FontSize":18,"Color":[0,0,0,1]},"Label":{"Position":[115,234],"Width":126,"Height":20,"Text":"AnotherButton","FontSize":18,"Color":[0,0,0,1]}}

你可以做到

var replaced = str.replace(/_\d+/g, '')
