将数组传递给函数并在Javascript中转义双引号

Question

I am generating dynamic HTML and want to pass an array to the calling function. The array is also being dynamically generated.

The contents of pinfoarray are somewhat like this "Ice Hockey","Junior Basketball","Ladies Soccer"

var theHost = "<a href='#someDialog' onclick='chnghost(' + pinfoarray + ');' data-toggle='modal' class='button'>Change</a>";

How can make it send the array to the calling function without an error.

Answer 1

How about making it like this :

var anchor = document.createElement('a');

anchor.href = '#someDialog';
anchor.setAttribute('data-toggle','modal');
anchor.className='button';

anchor.onclick = function(){
  chnghost(pinfoarray);
}

Answer 2

您需要关闭字符串双引号以放置一个javascript变量：

var theHost = "<a href='#someDialog' onclick='chnghost('" + pinfoarray + "');' data-toggle='modal' class='button'>Change</a>";

Answer 3

You need to properly terminate the string and encode the parameter. You also need to guard against reserved characters in your data ( escapeHtml ).

var theHost = "<a href='#someDialog' onclick='chnghost(" + escapeHtml(JSON.stringify(pinfoarray)) + ");' data-toggle='modal' class='button'>Change</a>";

If you're using jQuery, you can implement escapeHtml like so:

function escapeHtml(text) {
    return $("<div/>").text(text).html();
}
