Can i have 2 function in one script in html?
0
My page has a multiple 'tab' which displaying different data.
Here is my function for tab.
function openEvt(evt, evtName) {
var i, tabcontent, tablinks;
tabcontent = document.getElementsByClassName("tabcontent");
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
tablinks = document.getElementsByClassName("tablinks");
for (i = 0; i < tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(" active", "");
}
document.getElementById(evtName).style.display = "block";
evt.currentTarget.className += " active";
}
My page will display a bar chart when user click 'Detail' tab.
This is my code for the chart.
I put it in the script with the function openEvt().
function setChart(){
var ctx = document.getElementById("detail");
var detail= new Chart(ctx, {
type: 'bar',
data: {
labels: {{ chartdata_labels|safe }},
datasets: [{
label: '# of votes',
data: {{ chartdata_data }},
borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero:true
}
}]
}
}
});
}
window.onload = setChart;
Here is my code for display the chart above a table of data.
<canvas id="detail" width="1200" height="400"></canvas>
It work fine when there is only one function-openEvt().
But when I add in the setChart(), the tab wont function and no any data is display.

I have found it! You use double brackets at data.labels, in JavaScript, we use single for those types, so it has to be single {labels:'whatever'} or into an array [{labels:'whatever'}]. Also, you have to define your text at labels, OR is not a choice.
