Question

这是我的 html 代码 :

<div id="cmdt_1_29d" class="dt_state2" onclick="sel_test(this.id)">
    <img id="cmdt_1_29i" onclick="dropit( cmdt_1_29 );"
         src="http://hitechpackaging.zes.zeald.com/interchange-5/en_US/ico_minus.png">
    <span class="dt_link">
        <a href="javascript://">CARTON &amp; BOARD</a>
    </span> 
</div> 
<div id="cmdt_2_31d" class="dt_istate1" onclick="sel_test(this.id)">
    <img src="/site/hitechpackaging/images/items/test.jpb ">
    <a href="https://secure.zeald.com/hitechpackaging/shop/CARTON%20%20%20%20BOARD/CORRUGATED%20%20CORNER%20BOARD?mv_pc=21497">CORRUGATED &amp; CORNER BOARD</a>
</div>

The dropit function modifies my img src which I dont want to, unfortunately I cant modify, Can I somehow read the data into array before it is being modified and that I can add the data back to the image.

要删除点击处理器 :

var i = document.getElementById( cmd1_1_29i );
i.onclick = null;

或者,如果您仍想拨打最初点击处理器 :

var i = document.getElementById( cmd1_1_29i );
_onclick = i.onclick;

i.onclick = function(e) {
    // do what you want here
    _onclick && _onclick.apply(this, [e]);
}
