if you want to modify the contents of weex"s input tag through code, this will be a bit of a hassle, for example, at first you set it to 123, and then you manually modify this 123 on UI, for example, to 12. Then you want to modify the code to 123, which is a tragedy. Variables bound through the value property of input do not have the effect of updating at this time. The variable bound by input must be changed to a non-123content first, and then to 123again. So it can work. But the change will be triggered twice. Is there any good way to solve the problem
