Javascript转义双引号两次

Question

I am having problems trying to display correctly the value of a text input field containing double quotes (").

Here is the code:

<script>
var locked;
function addHTML(html,id,replace){
    if(locked!=false){
        if(replace==true) document.getElementById(id).innerHTML = html;
        else document.getElementById(id).innerHTML = document.getElementById(id).innerHTML + html;
    }
}
</script>
<DIV id="divvalues">
    <div onclick='javascript:addHTML("<INPUT type=\"text\" id=\"inputvalues\" name=\"values\" value=\"Click on me, \"in double quotes\", click on me\" required size=53 />","divvalues",true); document.getElementById("inputvalues").focus();'>
        <span>Click on me, "in double quotes", click on me</span>
    </div>
</DIV>

As a result, only Click on me, is displayed in the input . Any idea on how I should escape the double quotes inside the value attribute?

Answer 1

It will probably be easier for you to debug if you create a function in your script instead of doing everything in your onclick.

Instead I would start by doing something like this:

<div onclick='yourFunction()'>

And in your Javascript:

function yourFunction()
{
    // code
}

\\“用双引号\\”在您的输入标签中添加了一个“标记。它们应该是”吗？

Answer 3

The best solution I have found is to move the HTML outside the onclick attribute and place it inside a Javascript var :

<script>
var locked;
function addHTML(html,id,replace){
    if(locked!=false){
        if(replace==true) document.getElementById(id).innerHTML = html;
        else document.getElementById(id).innerHTML = document.getElementById(id).innerHTML + html;
    }
}

var divvalueshtml = '<INPUT type="text" id="inputvalues" name="values" value="Click on me, &quot;in double quotes&quot;, click on me" required size=53 />';
</script>
<DIV id="divvalues">
    <div onclick='javascript:addHTML(divvalueshtml,"divvalues",true); document.getElementById("inputvalues").focus();'>
        <span>Click on me, "in double quotes", click on me</span>
    </div>
</DIV>
