Jquery with 3. The text () why there is an access to content is empty?-CodePudding

 
Var TDS=$(this). The parent (). The parent () prevAll (); 
Var name=($(TDS [0]). The text ()); 
Var type=($(TDS) [1]. The text ()); 
Var price=($(TDS) [2]. The text ()); 
Alert (price);

$(this) is a label, the name and type can correct values, only price is empty
The name and type the background value is a string type, the price is double, but should be ok with this?
