JavaScript函数没有被调用？

所以我有一个按钮

<a class="btn btn-primary" id="btnAdd" href="#" onclick="ChangesJs.AddPlayList()"> <i class="fa fa-fw fa-plus fa-lg"></i>Add  </a>

---

当我在文本字段中失去焦点时，不会显示任何验证。

初始加载后在dom中创建的元素需要添加一个事件侦听器

function AddPlayList() {
var form = "<div class='form-group col-sm-3 clscommercial_" + addPlayList + "' style='display:none;' ><label>Break No.</label> <span class='red_color'>* </span><input class='form-control' id='txtBreakno_" + x + "' maxlength='2' onblur='ChangesJS.IsNumeric(this)' placeholder='Break No.' type='text'></div>";

// append it to the DOM....

var element = document.getElementsByClassName("clscommercial_" + addPlayList);
    element.addEventListener('change', function() { 
        CommonJs.HideErrorMessage(this);
    }, false);

}

如何在HTML中包含

AddPlayList

函数？@ThumChoonTat我通过script标签添加了脚本，并给出了js文件的位置，我想

onclick=“AddPlayList（）”

willdo@ThumChoonTat不，未定义AddPlayList（）。您是否在控制台中看到任何错误或消息？

function IsNumeric(selectinput) {
        var _value = selectinput.value;
        var ID = selectinput.id;
        if (_value !== "" && !$.isNumeric(_value)) {
            $("#div_" + ID).show();
            $("#span_" + ID).html("Please Enter numeric value !");
            selectinput.value = "";
            selectinput.focus();
        }
    }

function AddPlayList() {
var form = "<div class='form-group col-sm-3 clscommercial_" + addPlayList + "' style='display:none;' ><label>Break No.</label> <span class='red_color'>* </span><input class='form-control' id='txtBreakno_" + x + "' maxlength='2' onblur='ChangesJS.IsNumeric(this)' placeholder='Break No.' type='text'></div>";

// append it to the DOM....

var element = document.getElementsByClassName("clscommercial_" + addPlayList);
    element.addEventListener('change', function() { 
        CommonJs.HideErrorMessage(this);
    }, false);

}

$('body').on('change', '.clscommercial', function() {
    // This will fire even on elements added programmatically as long 
    // as your top selector is (body) was created on page load.
    CommonJs.HideErrorMessage($(this)[0]);
)};
