无法在php中调用函数onfocus事件

Question

I am not able to call a functions on onfocus and onblur events, both perfectly working in html but not in php here is code in php:

echo "<input value='Enter Name' onfocus= 'areaOnFocus(text1, 'Enter Name')' onblur='areaOnBlur(text1, 'Enter Name')' type='text' name='text1' id='text1'>";

both functions are called in script tag. I am sure that call to function is not made in this case as I am alerting in script tag , but nothing happen.

thank you in advance.

Well you're messing up with quotes there. I think you're using single quotes everywhere to avoid problems with the double quotes enclosing the string, but then you have this problem:

onfocus= 'areaOnFocus(text1, 'Enter Name')'

the single quote starts the string at areaOnFocus and ends it before Enter name .

You can either play with double quotes spamming like this:

echo "<input value=\"Enter Name\" onfocus=\"areaOnFocus(text1, 'Enter Name')\" onblur=\"areaOnBlur(text1, 'Enter Name')\" type=\"text\" name=\"text1\" id=\"text1\">";

or - better - put the HTML code outside PHP blocks.
