I am looking for the correct syntax to add content to an element using innerHTML. Here is an example that isn't working as expected:
openNewWindow: function(content) {
popupWin = window.open(content,
'open_window',
'menubar, toolbar, location, directories, status, scrollbars, resizable, dependent, width=640, height=480, left=0, top=0')
},
for (var index in mv.exifImages) {
ele.innerHTML += "<p onclick = openNewWindow(mv.exifImages[index]> image" + index + "</p>";
}
It seems that way to me. The variable index is confined to local scope.
for (var index in mv.exifImages) {
ele.innerHTML += "<p onclick = 'openNewWindow(\"" + mv.exifImages[index] + "\")'> image" + index + "</p>";
}
To insert text inside an element, use the appendChild method:
const targetElement = document.getElementById("target-element");
const newText = document.createTextNode("New text to be inserted");
targetElement.appendChild(newText);
Using appendChild is preferred over directly manipulating innerHTML as it does not interfere with existing event listeners, such as onclick events. More information on this topic can be found here:
Preventing Event Listener Loss When Appending to InnerHTML
The issue does not lie with innerHTML, but rather with the structure of your code.
openNewWindow: function(content) {
popupWin = window.open(content,
'open_window',
'menubar, toolbar, location, directories, status, scrollbars, resizable, dependent, width=640, height=480, left=0, top=0');
// call to window.open ended here
},
// based on the openNewWindow definition and preceding comma,
// it appears we are within an object declaration!
// You should avoid embedding a for loop directly within an object declaration!!!
for (var index in mv.exifImages) {
ele.innerHTML += "<p onclick = openNewWindow(mv.exifImages[index]> image" + index + "</p>";
}
Place your for loop in a more appropriate location, such as inside a function, or provide details about the specific error you encountered.
