Object array does not execute the "if" when call a method with the forEach but when I move the if inside of the forEach it works, I am trying to figure out why is not trigger the if inside the object when run the forEach.
There is a var (responseFlag) with the default value (false) so if you need to change the html render just change it (true/false) when the button is clicked.
var responseFlag = 'false',
targetRender = document.getElementById('targethtml'),
templateTrue = '<h2>true</h2>',
templateFalse = '<h2>false</h2>';
//
objDef = {
"objDefs" : [
{
"UIhtml": responseFlag == 'true' ? templateTrue : templateFalse // does not works
// "UIhtml": responseFlag // this works
}
]
};
//
UI_exc = {
outputResult: function() {
objDef.objDefs.forEach(function(key, value){
targetRender.innerHTML =
// responseFlag == 'true' ? templateTrue : templateFalse // this works
key.UIhtml // does not works
console.log(responseFlag)
});
},
clickAction: function() {
document.getElementById('goRender').addEventListener("click", function(){
responseFlag = 'true' // render html base true/false
console.log(responseFlag);
UI_exc.outputResult()
});
}
};
UI_exc.clickAction();<button id="goRender">Click</button>
<div id="targethtml">[ N ]</div>CodePudding user response：
The problem I guess is that object is initialized and the UIhtml property is assigned there, I think you should change UIhtml to a function and then call it:
... = key.UIhtml()
console.log(responseFlag)
CodePudding user response：
When creating object literals, the declared properties is not a string, rather it is a just a reference to some value e.g strings, numbers, booleans, objects...
Change the "UIhtml" to UIhtml.
