Why Cannot Read A TUniEdit Populated With Local Store Value?

[Frederick]

I am attempting to validate a TUniEdit that is populated with a local store item. In order to do the validation, I need to get the Text property of the TUniEdit control.

However, when I attempt to get the Text value, It is not the current value after the read but the value before the read.

In the example video, I want to get the value of "111" but I get the blank value (value before I save to local storage) or "222" (the current value before I click the Get button).

How do I get the correct value after the local store is read?

Note: I have attached a testcase.

Hello,

You have to Set Key, before.

I modified your code, see in attachment...

Hi Abaksoft,

I have already set the code correctly as shown below:-

      with edtText.JSInterface do
         JSCall('setValue', [jsstatement('localStorage.getItem("TEST")')]);      // important : Key must be Quoted " "
      // lblValue.Caption:=edtText.Text;   // Redundant
      lblValidate.Caption:=edtText.Text;  // Nothing shows from this line

edtText shows the correct value but lblValidate's caption shows nothing.
