如何从另一个函数内部调用此javascript函数？

Question

pic_display+="<img src='"+pic_url+"' onClick='swapImage("+pic_url+");'>

I am adding an image to the innerHTML of a div with the code above. I want to call the function swapImage(pic_url) whenever I click on the image.

I have still not figured out the syntaxes in javascript, always confuse them with php.

How should it be written ?

Thanks

Answer 1

您可以使用变量而不是字符串来转储引用问题：

... onclick="swapImage(this.src)" ...

Answer 2

Should be like this onClick='swapImage(\\""+pic_url+"\\");'

Note you need to quote the pic URL when it is the argument since you are meaning to use a string and not a variable.

Answer 3

Instead of

onClick='swapImage("+pic_url+");'>

try

onClick='swapImage(\""+pic_url+"\");'>

Answer 4

You need to wrap the function argument in quotes like you have with the src attribute. For example.

  pic_display+="<img src='"+pic_url+"' onClick='javascript:swapImage(\""+pic_url+"\");'>
