提交表格中添加button后自动提交问题

Jun 20, 2016 pm 12:37 PM

我想在一个表格中,添加一个button按钮,按下button时,只是要获取位置并填入,并不要提交。可是我把button放在表格里面后,只要按了button后,表格就会自动提交了。应该怎么写才按下button后不提交呢?

<form action="{p1::U('News/index')}" method="post" id="form" name="form"><p><div id="preview"></div></p><p class="tit">您的姓名</p><p><input name="username" type="text" class="wenbenkuang" size="30" maxlength="16"></p><p class="tit">联系方式</p><p><input name="contact" type="text" class="wenbenkuang"  size="30" maxlength="100"></p><p class="tit">事件描述</p><p><textarea name="comments" cols="37" rows="11" style="width:97%;height:200px;font-size:16px;"></textarea></p><p class="tit">我的位置(如不确定,可点击我在哪儿)</p><p><input name="address" type="text" class="wenbenkuang" id="address" size="30" maxlength="100"></p><p><button class="btn2" id="getLocation" >我在哪儿</button></p><p><input type="submit" value="提交" name="tijiao"></p></form>

这个是调用jssdk的位置接口,获得位置。
	wx.ready(function () {  document.querySelector('#getLocation').onclick = function () {    wx.getLocation({    	type: 'gcj02',      success: function (res) {        // alert(JSON.stringify(res));        var lat = res.latitude;        var lng = res.longitude;        var latLng = new qq.maps.LatLng(lat, lng);           geocoder = new qq.maps.Geocoder({             complete: function (result) {                      signin_info = result.detail.addressComponents.province + result.detail.addressComponents.city                                    + result.detail.addressComponents.district + result.detail.addressComponents.street;                       $("#address").val(signin_info);                       }                   })                   geocoder.getAddress(latLng);               },     	 	cancel: function (res) {       				 alert('用户拒绝授权获取地理位置');      }    });  };

点击 我在哪儿 不会出现提交

点击 我在哪儿 不会出现提交



我这样写,然后点击 我在哪儿 然后会出现整个表格都提交了 会不会跟我后台写的  if (IS_POST)     有关系 ?
我点击我在哪儿的时候,我只是要运行下面的js那段代码而已 

你是不是点错了?
点击   我在哪儿   是不会提交的
或者你是不是
点击   提交   了?

点这个不会提交的。要点提交才会。

button自带type="submit",所以会提交
加个type="button"就不会提交了
或者直接改成

把type设置成button就不会提交

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
