Hello, how are you? I wanted to pass a variable that contains a result into a frame that contains a chart and then the chart would use that value and plot it on the chart.
I'm programming in Ionic 3, HTML, JavaScript and SCSS.
How do I get the variable that is in JavaScript and play within the frame that is loading in HTML?
This question already exists in the SO in English, but to facilitate your understanding I will give a translated
On the page where the iframe will appear:
function myFunction(){
$('#meuIframe').attr('src', "meuIframe.html?param1=value1¶m2=value2");
}
Inside your iframe:
function getParamValue(paramName) {
var url = window.location.search.substring(1); // Pega as variaveis na url
var qArray = url.split('&'); // pega os pares de chave e valores
for (var i = 0; i < qArray.length; i++) {
var pArr = qArray[i].split('='); // Separa a Chave do Valor
if (pArr[0] == paramName)
return pArr[1]; // Retorna o Valor
}
}
If you want to get a specific parameter use:
var param1 = getParamValue('param1');
