我正在使用table2excel插件,这样我就可以将表内容下载到excel文件中。它第一次工作正常,但它只允许我每页加载一次下载。
我尝试将$("#export").click(function(){
更改为$("#export").on('click', function(){
,但这不起作用。 $(' #export'。)点击是在doc ready
// click function on page
$("#export").click(function(){
$("#table2excel").table2excel({
// exclude CSS class
exclude: ".noExl",
name: "Excel Document Name"
});
});
// external js file that gets called
//table2excel.js
;(function ( $, window, document, undefined ) {
var pluginName = "table2excel",
defaults = {
exclude: ".noExl",
name: "Table2Excel"
};
// The actual plugin constructor
function Plugin ( element, options ) {
this.element = element;
// jQuery has an extend method which merges the contents of two or
// more objects, storing the result in the first object. The first object
// is generally empty as we don't want to alter the default options for
// future instances of the plugin
this.settings = $.extend( {}, defaults, options );
this._defaults = defaults;
this._name = pluginName;
this.init();
}
Plugin.prototype = {
init: function () {
var e = this;
e.template = "<html xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns=\"http://www.w3.org/TR/REC-html40\"><head><!--[if gte mso 9]><xml>";
e.template += "<x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions>";
e.template += "<x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>";
e.tableRows = "";
// get contents of table except for exclude
$(e.element).find("tr").not(this.settings.exclude).each(function (i,o) {
e.tableRows += "<tr>" + $(o).html() + "</tr>";
});
this.tableToExcel(this.tableRows, this.settings.name);
},
tableToExcel: function (table, name) {
var e = this;
e.uri = "data:application/vnd.ms-excel;base64,";
e.base64 = function (s) {
return window.btoa(unescape(encodeURIComponent(s)));
};
e.format = function (s, c) {
return s.replace(/{(\w+)}/g, function (m, p) {
return c[p];
});
};
e.ctx = {
worksheet: name || "Worksheet",
table: table
};
window.location.href = e.uri + e.base64(e.format(e.template, e.ctx));
}
};
$.fn[ pluginName ] = function ( options ) {
this.each(function() {
if ( !$.data( this, "plugin_" + pluginName ) ) {
$.data( this, "plugin_" + pluginName, new Plugin( this, options ) );
}
});
// chain jQuery functions
return this;
};
})( jQuery, window, document );

由于jquery插件中的代码块,它只执行一次:
$.fn[ pluginName ] = function ( options ) {
this.each(function() {
if ( !$.data( this, "plugin_" + pluginName ) ) {
$.data( this, "plugin_" + pluginName, new Plugin( this, options ) );
}
});
// chain jQuery functions
return this;
};
$("#table2excel")
仅初始化一次,后续跳过。
对代码的某些更改进行了一些更改:
$("button").click(function(){
var $table = $('#table2excel');
$table.removeData(); //data is removed, previous when data existed was preventing initialization of table2excel
$table.table2excel({
exclude: ".noExl",
name: "Excel Document Name"
});
});

其他
$("#export").click(function(){
$("#table2excel").table2excel({
// exclude CSS class
exclude: ".noExl",
name: "Excel Document Name"
}); });
如果他们第二次点击它,您希望以不同的方式发生什么?
您可能感觉只是工作一次,是因为它已经应用了更改,所以如果再次点击则完成工作时没有其他操作要做。
这是假设脚本一直没有错误。如果有错误,您可以通过在Chrome中按f12来检查。在屏幕的右上角,您应该看到是否有错误。如果它正在运行,然后在单击操作期间失败,这可能是您找到问题的来源。

根据脚本(jquery.table2excel.js)的困扰不允许您多次运行它,因此要解决此问题首先添加 在文件脚本的末尾,在页面加载后添加指向脚本的链接,现在你可以编写函数来调用导出到 excel
<script>
$(document).ready(function(){
$("#MyplaginEXL").attr("src","/TableToExcel/jquery.table2excel.js")
});
function PrintTable()
{
$("#IdTable").table2excel({
exclude: ".noExl",
filename: "FileName",
fileext: ".xls",
exclude_img: true,
exclude_links: true,
exclude_inputs: true,
preserveColors: true
});
}
