Click A Button On A Web Site Automatically With Javascript
I modify a code like that, for click a checkbox. Such as, Is there a any problem about button name or id. I could see just name and class. Is this a problem for work?
Solution 1:
Problem 1: getElementById should be getElementByName
Based on your screenshot, the input item you are trying to reference is:
<input name="chkA5" class="formCheckBox"type="checkbox" value="ON"></input>
and you are trying to getElementById()
document.getElementById("chkA5").checked = trueHowever, there is no id declared, so you will have to get the item by the name, using getElementByName():
document.getElementsByName("chkA5")[0].checked = true;
Problem 2: Your javascript has errors
This line will cause your script block fail:
var chkA5 = "button"class=formCheckBox type=checkbox value=ON name=chkA5
If you require a complete code sample, here is an example:
<html><head></head><body><inputname="chkA5"class="formCheckBox"type="checkbox"value="ON"></input></body><script>
(function() {
document.getElementsByName("chkA5")[0].checked = true;
})();
</script></html>Note: Make sure that the script block is at the end of your html, like in your example code provided.
