Call submit button function from jquery?
提问by James123
I want call OnClick function on page load with out user clicking. Can we do that in jQuery or javascript?
我想在页面加载时调用 OnClick 函数而无需用户点击。我们可以在 jQuery 或 javascript 中做到这一点吗？
<input name="ctl00$PlaceHolderMain$ButtonSection$RptControls$BtnSubmit"
class="ms-ButtonHeightWidth"
id="ctl00_PlaceHolderMain_ButtonSection_RptControls_BtnSubmit"
accessKey="o" onclick="javascript:WebForm_DoPostBackWithOptions(new
WebForm_PostBackOptions("ctl00$PlaceHolderMain
$ButtonSection$RptControls$BtnSubmit",
"", true, "", "", false, true))"
type="button" value="OK"/>

$(document).ready(function() {
$("#ctl00_PlaceHolderMain_ButtonSection_RptControls_BtnSubmit").click();
});
This will trigger the clickevent on the element with the supplied id, and it will run when the document is fully loaded.
这将click在提供的元素上触发事件id，并在文档完全加载时运行。

You can call trigger and pass the type of event to trigger.
您可以调用触发器并将事件类型传递给触发器。
$('#ctl00_PlaceHolderMain_ButtonSection_RptControls_BtnSubmit').trigger('click');

You imply in the question title that the button you want to click is a submit button. If so you would be better off calling the submit method of the form instead of the click event of the submit button.
您在问题标题中暗示要单击的按钮是提交按钮。如果是这样，您最好调用表单的提交方法而不是提交按钮的点击事件。
document.forms["myform"].submit()
回答by MikeM
var $btnSubmit = $('#ctl00_PlaceHolderMain_ButtonSection_RptControls_BtnSubmit');
// Either method will work:
// Method 1: jQuery has a click event pre-defined
$btnSubmit.click();
// Method 2: some events (such as newly defined HTML5 events)
// may not be pre-defined, so .trigger('[event]') is a way to
// explicitly invoke that event
$btnSubmit.trigger('click');

Or with javascript inside the body:
或者在正文中使用 javascript：
<body onload="javascript:document.getElementById('ctl00_PlaceHolderMain_ButtonSection_RptControls_BtnSubmit').click()" ></body>
The trick is to get the element and call the click method.
诀窍是获取元素并调用 click 方法。
