</div>
<h5 id="xxx">jquery</h5>
<script>
function adauga() {
var cuvant = document.getElementById('inp').value;
var para = document.createElement("p");
para.setAttribute("id","z");
var node = document.createTextNode(cuvant);
para.appendChild(node);
var element = document.getElementById("div1");
element.appendChild(para);
}
function sterge() {
var parent = document.getElementById("div1");
var child = document.getElementById("z");
parent.removeChild(child);
}
$(document).ready(function(){
$("p").click(function(){
$("p").hide();
});
});
</script>
</body>
</html>
解决方案
试试这个:
$(document).ready(function(){
$("body").on("click","p", function(){
$("p").hide();
});
});
片段:
function adauga() {
var cuvant = document.getElementById('inp').value;
var para = document.createElement("p");
para.setAttribute("id","z");
var node = document.createTextNode(cuvant);
para.appendChild(node);
var element = document.getElementById("div1");
element.appendChild(para);
}
function sterge() {
var parent = document.getElementById("div1");
var child = document.getElementById("z");
parent.removeChild(child);
}
$(document).ready(function(){
$("body").on("click","p", function(){
$(this).hide();
});
});
