In my current project, I'm attempting to compare specific values of an initial object with an updated object in order to disable a button if they are the same. However, despite making changes, the button remains disabled:
setDisabled() {
return this.selectedItem.color === this.selectedItemInitial.color &&
this.selectedItem.price === this.selectedItemInitial.price;
},
I'm puzzled as to what is causing this issue and why the boolean value isn't changing. Any insights?
Your custom function setDisabled is currently only executed once, when the component is initially rendered and not when the data within the component changes.
To ensure that buttonDisabled (which should be renamed for better clarity) updates dynamically with changes in the component's data or props, it should be moved to the computed properties section of the component:
computed: {
buttonDisabled: function(){
return this.selectedItem.color === this.selectedItemInitial.color && this.selectedItem.price === this.selectedItemInitial.price
}
}
You can then use it in your HTML like this:
<!-- Remember not to use parentheses when using a computed property -->
<button :disabled="buttonDisabled"> ACTION </button>
It is important to properly instantiate your component data in order to avoid any potential logic errors.
A recommended approach is to use the method like this:
<button :disabled="setDisabled()"> ACTION </button>
Alternatively, consider changing it to a computed property for better organization:
computed: {
setDisabled: function(){
//place your logic here
}
}
Another option is to complete the entire process within the template, which will vary depending on how the variables are configured.
<button :disabled="selectedItem.color === selectedItemInitial.color">Click</button>
